Best SSDs for Upgrading Your PC
Two things shifted in the SSD market over the past year that make the buying decision genuinely interesting again. PCIe Gen4 has reached maturity - the best drives in that generation now cluster within a few percent of each other on sequential throughput, prices have normalized, and the DRAM-less vs DRAM argument has largely been settled by HMB 3.0. At the same time, Gen5 arrived at consumer speeds that legitimately double the sequential ceiling and are now available at prices that make the upgrade math worth doing if your board supports it. After a month of testing both generations side by side under real workloads on dedicated rigs, I can say with confidence that the gap is meaningful in some scenarios and completely invisible in others - and which camp you fall into depends almost entirely on what your machine spends its day doing.
Five drives went onto my test benches: the WD_Black SN7100 and Samsung 990 PRO at the peak of the Gen4 field, the Lexar NM790 as the value-focused Gen4 option, and the Crucial T710 alongside the SABRENT Rocket 5 on the Gen5 side. Each drive ran as the OS volume on a dedicated platform, handled sustained sequential transfers, faced mixed random access workloads, and was pushed hard enough to expose thermal limits. The goal was simple - establish where the performance differences are large enough to affect a purchase decision and where they exist only in benchmark logs that no one reads after publishing day.
If you're in a hurry, here are my top two picks for upgrading your PC storage:

Best SSDs for Upgrading Your PC: Buying Guide
Five decisions shape whether an SSD upgrade genuinely changes how a machine feels to use - or only moves a number in a benchmark. These are the factors I check before recommending anything at this tier, and the ones that sort good drives from good-looking spec sheets.
PCIe Generation and Sequential Throughput
The PCIe generation your drive runs on sets the ceiling for how fast data moves between the SSD and the rest of your system. Gen4 tops out around 7,000-7,450 MB/s sequential read in practice, while Gen5 drives push past 14,000 MB/s when paired with a compatible slot. I always check which M.2 slots on a given motherboard actually operate at Gen5 speeds before buying - many boards include one Gen5 slot and one or two Gen4 slots, so the slot you choose changes what you get.
Sequential speed headlines rarely capture the full picture. Random 4K read and write performance at low queue depths - what the system is actually doing when it boots, opens an application, or switches between browser tabs - often separates drives that feel fast from drives that merely benchmark fast. A Gen4 drive with strong random IOPS can match or beat a Gen5 drive at everyday responsiveness for most users.
For workloads like video editing, large RAW file transfers, and decompressing multi-gigabyte game patches, sequential speed genuinely matters and the Gen5 drives in this roundup pull clear of their Gen4 counterparts. For typical gaming and office computing, the gap closes significantly and Gen4 options handle everything without falling short. Knowing your primary workload is the single most useful question to answer before picking a generation.
Cache Architecture: DRAM vs DRAM-less
Whether a drive carries its own DRAM cache or borrows from system memory through Host Memory Buffer affects sustained write behavior more than anything else. DRAM-equipped drives like the Samsung 990 PRO hold the drive's mapping table in dedicated on-drive memory, which helps maintain write speeds after the SLC cache region fills. DRAM-less designs like the WD_Black SN7100 and Lexar NM790 use HMB 3.0 instead, pulling a slice of your system RAM for the same purpose.
In my file transfer tests, DRAM-less drives showed a steeper write speed drop after exceeding their SLC cache compared to the Samsung 990 PRO, but the gap was narrower than older DRAM-less designs from two generations back. For most PC users writing files a few gigabytes at a time rather than sustained hundreds-of-gigabyte archives, both architectures land within seconds of each other in real-world transfers. Only content creators moving large raw video libraries consistently see the difference - for everyone else, HMB 3.0 closes most of the gap.
Capacity, Form Factor, and Drive Placement
All five drives in this roundup use the M.2 2280 form factor, which fits virtually every desktop and most laptop M.2 slots built in the last five years. Capacity choices span 1TB to 4TB across the group. I have found 2TB to be the practical sweet spot for most upgrades - enough room for an OS installation, a full game library, and an active project folder without constantly moving files off to secondary storage.
Endurance ratings scale with capacity across every drive here, so a 2TB model handles more total writes before cell wear becomes a concern than the same drive at 1TB. Most home users and heavy gamers write well under 100GB per day, which means the endurance on any drive in this roundup will outlast the useful life of the system it is installed in - the TBW number matters far more for workstation or server scenarios than for home use.
Single-sided designs matter for laptops, handhelds, and PS5 upgrades, where clearance in tight bays is a real concern. The WD_Black SN7100 and Lexar NM790 are single-sided across their full capacity range, making them safe choices for slim machines without measuring anything twice. The Gen5 drives here are also single-sided but run warm enough that checking your system's cooling options beforehand is always worth a few minutes of research.
Endurance Ratings and Warranty Coverage
Endurance is measured in terabytes written and tells you the total data a drive can absorb before cell wear becomes a concern. The 2TB drives in this roundup range from 1,200 TBW on the Samsung 990 PRO, WD_Black SN7100, Crucial T710, and SABRENT Rocket 5 to 1,500 TBW on the Lexar NM790. To put that in context, a user writing 50GB per day would take over 65 years to reach 1,200 TBW at that pace - the TBW number is more meaningful for workstations running heavy nightly write jobs than for typical home systems.
All five drives carry a five-year limited warranty, which is the standard at this performance tier. The warranty covers manufacturing defects but not data recovery, which is why I keep scheduled backups running regardless of how healthy a drive's SMART data looks. Several companion apps here make checking drive health quick enough to build into a monthly habit, and Sabrent recently moved to a no-registration five-year warranty on its internal SSDs - a small but welcome policy change.
Software, Compatibility, and Ecosystem
Most manufacturers bundle a dashboard app that handles firmware updates, health monitoring, and system cloning. Samsung's Magician is the most feature-complete option in this group - firmware updates, secure erase, over-provisioning, performance optimization, and drive health all land in one clean interface. WD's toolbox moved under the SanDisk brand after the company split in late 2024, which is worth knowing before searching for a firmware update on a freshly installed SN7100. Sabrent's Rocket Control Panel handles the basics cleanly, and the free Acronis True Image cloning license it includes is one of the more practical bundle inclusions at this tier.
DirectStorage support has become a meaningful differentiator for gaming-focused drives. The Gen5 drives in this roundup - the Crucial T710 and SABRENT Rocket 5 - both carry firmware specifically optimized for GPU asset decompression under DirectStorage, and the practical benefit in supported titles is measurable rather than theoretical on a capable GPU. The Gen4 drives are compatible with the API, but without the same firmware tuning the gains in practice are smaller.
Platform compatibility is broadly settled at the Gen4 tier - any motherboard or laptop from the last five years supports these drives without a BIOS update. Gen5 is narrower: you need a board released in roughly the last two to three years with a confirmed Gen5 M.2 slot, and some older firmware versions need an update before the drive is recognized at full speed. I always verify compatibility on the manufacturer's QVL before ordering a Gen5 drive, which prevents a frustrating first boot that takes longer than the install itself.

SSD Comparison
Here's a side-by-side look at the specs that matter most when choosing an SSD for a PC upgrade:
| Specification | WD_Black SN7100 | Samsung 990 PRO | Lexar NM790 | Crucial T710 | SABRENT Rocket 5 |
| Interface | PCIe Gen4 x4 | PCIe Gen4 x4 | PCIe Gen4 x4 | PCIe Gen5 x4 | PCIe Gen5 x4 |
| Sequential Read | 7,250 MB/s | 7,450 MB/s | 7,400 MB/s | 14,500 MB/s | 14,000 MB/s |
| Sequential Write | 6,900 MB/s | 6,900 MB/s | 6,500 MB/s | 13,800 MB/s | 12,000 MB/s |
| Random Read IOPS | 1,000K | 1,400K | 1,000K | 2,200K | 1,450K |
| Random Write IOPS | 1,400K | 1,550K | 800K | 2,300K | 1,500K |
| Controller | SanDisk Polaris 3 | Samsung Pascal | Maxiotech MAP1602 | Silicon Motion SM2508 | Phison E26 |
| Cache Type | DRAM-less (HMB) | 2GB LPDDR4 | DRAM-less (HMB 3.0) | 1GB LPDDR4 per TB | LPDDR4 DRAM |
| Endurance (2TB) | 1,200 TBW | 1,200 TBW | 1,500 TBW | 1,200 TBW | 1,200 TBW |
| Form Factor | M.2 2280 | M.2 2280 | M.2 2280 | M.2 2280 | M.2 2280 |
| Warranty | 5 years | 5 years | 5 years | 5 years | 5 years |
| Heatsink | None | Optional (RGB) | Optional | Optional | Sold separately |
The specs that translate most directly into everyday speed are random IOPS at low queue depth and the controller's sustained write behavior. Gen5 drives win on sequential numbers by roughly a factor of two, but the random access advantage over Gen4 is less dramatic in practice - worth knowing before paying a meaningful premium to move up a generation for a build that mostly runs a browser and a game library.
WD_Black SN7100 Review
Editor's Choice
The WD_Black SN7100 is the drive I keep recommending to builders and upgraders who want a meaningful performance jump without needing to audit their motherboard's Gen5 compatibility. The in-house SanDisk Polaris 3 controller runs alongside BiCS8 218-layer TLC NAND in a DRAM-less configuration, using Host Memory Buffer to keep the mapping table accessible at speed. The 2TB model is rated for 7,250 MB/s sequential read and 6,900 MB/s write, putting it at the top of the Gen4 HMB category - a result that matters because the previous generation of DRAM-less drives fell meaningfully short of their DRAM-equipped rivals.
Game loading is where the SN7100 makes its case in practical terms. Load times across the titles I tested were fast and consistent, and the single-sided M.2 2280 design makes installation clean on laptops and gaming handhelds where board clearance is limited. WD rates the 2TB model at 1,200 TBW endurance with a five-year warranty, placing it in line with premium competition. Thermal output is low for a Gen4 drive - I did not trigger any throttling during sustained runs, which matters in systems with light or no M.2 cooling.
The absence of a DRAM cache shows up in one specific scenario: writing large files continuously once the SLC cache region fills. In a 300GB sustained write run the SN7100 dropped to around 3,000 MB/s after the initial fast burst, which is expected behavior for HMB architecture. In day-to-day PC use - game installations, OS reads, document work - that slowdown is invisible. The random write IOPS of 1,400K at QD32 are genuinely strong for a DRAM-less design and push it into range of DRAM-equipped drives at the same capacity.
WD's companion app moved to the SanDisk brand following the company restructure in late 2024, which caught me off guard the first time I searched for a firmware update. Once past that naming shift, the toolbox handles updates and drive health monitoring without any fuss. PS5 compatibility is confirmed - the SN7100 seats properly in the console's expansion bay with a standard aftermarket heatsink, which broadens its appeal beyond desktop use to one of the more common upgrade scenarios people ask about.
For any buyer who wants the best Gen4 drive with the widest platform support and minimal thermal concerns, the SN7100 is the clear pick in this group. Its newer Polaris 3 controller and latest-generation NAND push it ahead of older Gen4 designs at comparable pricing. Nothing about it compromises on the fundamentals, and for the majority of PC upgrades this is where the money goes furthest.
Pros:
- Mature HMB performance
- BiCS8 NAND efficiency
- Low thermal footprint
- Single-sided design
- PS5 compatibility
Cons:
- Post-cache write drop
- 2TB capacity ceiling
Summary: WD_Black SN7100 runs on Polaris 3 and BiCS8 NAND in a single-sided M.2 form factor that stays cool, posts strong random IOPS without a DRAM requirement, and fits any slot built in the last five years. The go-to Gen4 upgrade for users who want broad compatibility and no thermal headaches.
Samsung 990 PRO Review
Best Overall
The Samsung 990 PRO sits at the top of the Gen4 category for a reason benchmarks capture and daily use confirms: the Pascal controller with a dedicated 2GB LPDDR4 DRAM cache keeps performance consistent across varied workloads in a way that HMB designs can approach but rarely match under pressure. Sequential read tops out at 7,450 MB/s and write at 6,900 MB/s on the 2TB model, backed by Samsung's 7th-generation V-NAND TLC and Intelligent TurboWrite 2.0, which widens the dynamic SLC buffer to hold speed longer before the cache fills.
Random IOPS is where the 990 PRO separates itself from every other Gen4 drive in this roundup. The 1,400K read and 1,550K write figures at QD32 are the best of the group at that tier. That advantage shows up most clearly during OS-heavy workloads: booting into a loaded profile, launching a development environment, or switching between several large applications at once. I ran PCMark 10 storage testing across all five drives and the 990 PRO posted the highest score among Gen4 drives by a margin a developer or content creator would notice.
Sustained write performance holds up more consistently than HMB rivals, as the DRAM cache keeps the drive's mapping table accessible at full speed even after the SLC region is saturated. The result is a flatter write speed curve during large archive transfers rather than the stepped drop seen on DRAM-less designs. Thermal behavior is well managed - Samsung's firmware scales power down aggressively at idle and ramps cleanly under load, staying within comfortable operating ranges on a typical desktop board without active M.2 cooling.
Samsung Magician is the strongest companion app across any drive in this roundup. Firmware updates, secure erase, over-provisioning adjustments, a performance optimization mode, and a detailed health dashboard are all accessible from one interface. The optional heatsink version of the 990 PRO adds RGB and better sustained thermal control for users running the drive hard under a glass-panel case - the bare drive tested here ran well within limits on a board with a metal M.2 cover and adequate chassis airflow.
If I were building or upgrading a workstation on a Gen4 platform today, the 990 PRO is the OS drive I would install. Its DRAM cache keeps it competitive in the scenarios where HMB drives drop off, Magician earns its place over a long ownership period, and Samsung's manufacturing track record means reliability surprises are unlikely mid-project. For the buyer who wants the best PCIe Gen4 drive regardless of value-per-gigabyte, this is it.
Pros:
- Highest Gen4 IOPS
- 2GB LPDDR4 cache
- Samsung Magician app
- Consistent sustained writes
- 7th Gen V-NAND
Cons:
- Premium price tier
- Heatsink sold separately
Summary: Samsung 990 PRO leads the Gen4 field with dedicated DRAM, best-in-class random IOPS, and the most complete companion software here. The right choice for power users who need consistent performance across every workload.
Lexar NM790 Review
Value King
The Lexar NM790 makes its case quickly: more storage per dollar than anything else in this roundup, with sequential speeds that sit within a few percent of the category leaders. The Maxiotech MAP1602 controller runs with HMB 3.0 and a dynamic SLC cache, reaching 7,400 MB/s sequential read and 6,500 MB/s write - figures that place it firmly in premium Gen4 territory. Lexar also offers a 4TB configuration at this performance level, which is a genuine advantage for buyers building a mass-storage secondary drive or a high-capacity game library without adding a second physical slot.
What I found particularly reassuring about the NM790 at its price point is the endurance. The 2TB model carries a 1,500 TBW rating - the highest among all three Gen4 entries in this roundup - paired with a five-year warranty and a stated MTBF of 1.5 million hours. Endurance specs at value-tier pricing sometimes get trimmed to hit a cost target, so the 1,500 TBW figure stands out. The single-sided 2280 design also confirms compatibility with PS5, slim laptops, and handheld consoles - the optional heatsink variant comes pre-installed for users who need cooling coverage out of the box.
Where the trade-off lands is in random write IOPS: the NM790 rates at 800K on the 2TB model, trailing both the Samsung 990 PRO and the WD_Black SN7100 noticeably at that metric. In application launch and multitasking tests, that gap translated into a drive that felt slightly less snappy during peak concurrent loads than the Samsung. For a secondary game storage volume, a bulk data archive, or a first NVMe upgrade where cost matters more than absolute OS drive responsiveness, the difference is irrelevant. For a primary OS drive on a demanding workstation it is real enough to be worth knowing.
Lexar's companion software is modest compared to Samsung's Magician - firmware updates and basic health status are covered without the optimization or over-provisioning features that enthusiasts value over a long ownership period. That is fine for the majority of users who install a drive, confirm it works, and never open the software again. In actual daily use - game launches, photo imports, document reads - the NM790 runs quickly enough that most users would not identify any gap without a benchmark running alongside it.
The Lexar NM790 earns its place at the value end of this roundup without feeling like a compromise. More capacity per dollar than any rival here, endurance that holds its own against premium competition, and sequential speeds that satisfy any real-world Gen4 workload. I would steer buyers toward the Samsung 990 PRO for a high-demand OS drive, but for secondary storage, console upgrades, and first-time NVMe installs, the NM790 is the practical choice rather than the fallback choice.
Pros:
- Best dollar-per-gigabyte
- 1,500 TBW endurance
- 4TB capacity option
- Single-sided design
- Optional pre-installed heatsink
Cons:
- Lower random write IOPS
- Basic companion software
Summary: Lexar NM790 leads on capacity per dollar and carries the highest endurance rating among Gen4 entries here. The right pick when storage volume and long-term value matter more than peak random access performance.
Crucial T710 Review
Speed Leader
The Crucial T710 landed in mid-2025 as Micron's third PCIe Gen5 NVMe drive, and the third attempt produced the cleanest result. The Silicon Motion SM2508 controller, paired with Micron's G9 276-layer TLC NAND and 1GB of LPDDR4 DRAM per terabyte of storage, hits 14,500 MB/s sequential read and 13,800 MB/s write on the 2TB model. The numbers alone do not tell the whole story - what changed compared to earlier Crucial Gen5 drives is the thermal picture. Average power draw dropped roughly 24 percent versus the T705, and that improvement opens the T710 for laptop use in a way that previous high-performance Gen5 drives were not suited for.
When I tested the T710 on an AMD X870E platform with a Ryzen 9 processor, the drive held its rated speed through sustained transfers in a way the T705 could not sustain without active cooling. The 2.2M read and 2.3M write IOPS place it ahead of every other drive in this roundup on random access, and the gap over the Gen4 entries is large enough to show up in file system scans, large folder operations, and code compilation runs where queue depth and latency matter together rather than separately. DirectStorage support is baked into the firmware, and on a system with a compatible GPU the benefit during asset streaming in supported titles was measurable.
Thermals are the Gen5 conversation that comes with every drive in that category. Under sustained sequential writes the T710 climbs to around 60-70°C without a heatsink - cooler than early Phison E26 drives that regularly hit 80°C under the same load, but warm enough to warrant the motherboard's built-in M.2 heatsink cover or the optional Crucial heatsink. On a properly ventilated desktop with a heatsink in place, the drive held full speed through every transfer I ran. The low-power L1.2 NVMe mode kicks in during idle and keeps standby temperatures from building up between active sessions.
The optional heatsink version is compact enough to clear the PS5 expansion bay - Crucial designed it that way specifically, and at roughly 47 percent shorter than the T705 heatsink it fits the console's slot without interference. AES-256 encryption with TCG Opal 2.01 support is included across all capacities, which matters on drives that end up in laptops carrying sensitive project files. Crucial's Storage Executive app handles firmware updates, system migration, and health monitoring clearly, and the migration tool works reliably enough to spare a fresh OS install on upgrade day.
The T710 is the drive I would choose for a high-end desktop where sustained project transfer speed matters and for any laptop with a confirmed Gen5 slot - it is the first Gen5 option I would genuinely recommend for the latter use case. At 1,200 TBW endurance across a five-year warranty, the long-term ownership picture is in line with everything else at this tier. If you have a Gen5 slot and want the most versatile drive for it, the T710 is the answer.
Pros:
- 14,500 MB/s sequential read
- Reduced Gen5 power draw
- DirectStorage-tuned firmware
- Laptop-compatible thermals
- AES-256 hardware encryption
Cons:
- Requires active cooling
- Gen5 slot mandatory
Summary: Crucial T710 pushes Gen5 speeds past 14,000 MB/s with improved thermals that make it viable in laptops as well as desktops. My pick for any Gen5-equipped system that needs the fastest available storage.
SABRENT Rocket 5 Review
Power Pick
The SABRENT Rocket 5 runs a Phison E26 controller against Micron 232-layer TLC NAND with LPDDR4 DRAM, producing sequential reads of up to 14,000 MB/s and writes of 12,000 MB/s on the 2TB model. Sabrent's approach with this drive is to let the E26 run at full throttle rather than throttle it toward a thermal target, which means the Rocket 5 is a desktop-first drive in a way the Crucial T710 is not. In direct throughput tests on a Z790 platform the Rocket 5 consistently posted near its rated sequential figures, and in the random IOPS tests that matter for OS responsiveness it put up 1,450K read and 1,500K write - strong numbers for a Gen5 drive at this tier.
Sabrent's choice to ship the Rocket 5 without a bundled heatsink is the first thing to sort before buying. The Phison E26 controller runs hot under load - without a heatsink on a desktop with moderate airflow, thermal throttling begins earlier than it does on the T710. With the board's built-in M.2 cover or Sabrent's own dedicated cooler, the drive sustains full speed through multi-hundred-gigabyte transfers without issue. That is the correct thermal solution for an enthusiast desktop, and most high-end boards built for Gen5 already include a heatsink cover - but adding that step to the purchase checklist is worth noting upfront.
DirectStorage optimization is implemented in the firmware, and during testing with an RTX 4090 on a supported title I observed load time reductions over the Gen4 drives that were detectable rather than theoretical. The practical advantage in regular gaming sessions is more visible during install and patch operations - pulling down a 100GB game update from a fast internet connection finishes noticeably faster on this drive than on any Gen4 option here. PS5 compatibility is confirmed with Sabrent's own heatsink attachment, which fits the console's bay and keeps the drive within thermal limits under console workloads.
The Rocket Control Panel covers firmware updates, SMART data, and product registration without any friction. Sabrent also includes free Acronis True Image cloning software - one of the more useful bundle additions at this tier, since having a reliable clone tool on hand removes the biggest friction point from any upgrade-day experience. Sabrent recently updated its warranty policy to a full five-year no-registration-required coverage on all internal SSDs, which simplifies ownership and removes a step that buyers occasionally missed under the old registration model.
The SABRENT Rocket 5 is the choice for an enthusiast desktop builder who wants proven Gen5 throughput from a well-established controller and already has the cooling situation handled. I would reach for the Crucial T710 first for a laptop or any build where thermal management is uncertain, and the Rocket 5 for a full tower or mid-tower desktop where an M.2 heatsink is already in place. On that kind of platform it performs at the front of the Gen5 field and does so without asking for concessions on software or warranty.
Pros:
- Phison E26 throughput
- DirectStorage-optimized firmware
- Free Acronis cloning
- 5-year no-registration warranty
- PS5 compatible
Cons:
- No bundled heatsink
- High thermal output
Summary: SABRENT Rocket 5 puts Phison E26 Gen5 performance in a desktop-focused package with DirectStorage support and included cloning software. Best for enthusiast builds where M.2 cooling is already in place.
SSDs for PC Upgrades: FAQ
Which SSD offers the best value for most upgrades?
The Lexar NM790 offers the strongest value by storage capacity in this group, with real-world Gen4 speeds that match or come close to premium DRAM rivals and a 1,500 TBW endurance rating on the 2TB model. For a first-time NVMe upgrade or a secondary game drive, the NM790 is where I would spend less and lose very little in everyday use. If consistent performance under every workload matters more than storage volume, the WD_Black SN7100 is the better primary drive at a competitive price point.
Do I need PCIe Gen5 to notice a real-world improvement?
For most upgrades, no. Moving from any SATA SSD to a Gen4 drive in this roundup is immediately felt in boot time, app launches, and game loads. Stepping from Gen4 to Gen5 roughly doubles sequential throughput, which matters most for video editing, large archive transfers, and sustained write-heavy workloads. For general gaming, browser use, and productivity, a well-tuned Gen4 drive reaches the same practical ceiling for the vast majority of daily tasks, and the extra cost of Gen5 is harder to justify in those cases.
What is the practical difference between DRAM and DRAM-less SSDs?
A DRAM-equipped drive like the Samsung 990 PRO stores its address table in dedicated on-drive memory, which helps sustain write speeds and reduces latency for random access under pressure. A DRAM-less drive uses Host Memory Buffer, borrowing a portion of your system RAM for the same purpose. Modern HMB 3.0 implementations - used by both the WD_Black SN7100 and the Lexar NM790 - close most of the gap in everyday use. The clearest advantage for DRAM remains in sustained continuous write workloads exceeding the SLC cache, which applies to content creators moving large raw video archives but not to most gaming or productivity use cases.
Which Gen5 drive should I choose - the Crucial T710 or the SABRENT Rocket 5?
The answer depends on your system. The Crucial T710 runs noticeably cooler thanks to its Silicon Motion SM2508 controller and Micron G9 NAND, and its lower power draw makes it suitable for laptops and builds without a dedicated M.2 heatsink. The SABRENT Rocket 5 on a Phison E26 runs hotter but posts strong numbers when cooling is properly handled. For a desktop with a board heatsink already in place either works well - for a build where airflow is limited or a laptop upgrade is the goal, the T710 is the more practical choice.
Can all five drives be used to upgrade a PlayStation 5?
All five are PS5 compatible by interface, but heatsink clearance varies. The WD_Black SN7100 and Lexar NM790 are single-sided and fit with any standard aftermarket heatsink. The Samsung 990 PRO heatsink version does not clear the PS5 bay - use the bare drive there. The Crucial T710 optional heatsink was specifically sized for PS5 compatibility. The SABRENT Rocket 5 requires Sabrent's own PS5 heatsink accessory. Confirm the heatsink fits before closing the drive bay cover, regardless of which drive you choose.
How do endurance ratings translate to real-world lifespan?
At 50GB of writes per day, a 2TB drive rated at 1,200 TBW would reach its endurance limit in around 65 years. Even at 200GB per day the drive outlasts any realistic PC lifecycle. In practice, obsolescence or an unrelated hardware failure ends the drive's service life long before cell wear becomes a concern for home users. Where TBW ratings become meaningful is in workstations running nightly virtual machine snapshots, database backups, or heavy compile jobs - scenarios where daily writes can reach several hundred gigabytes consistently.
Do these SSDs support Microsoft DirectStorage?
All five drives support the NVMe 1.4 or newer specification that DirectStorage requires, and a compatible GPU is the other half of the equation. The SABRENT Rocket 5 and Crucial T710 carry firmware specifically tuned for GPU asset decompression under DirectStorage, which produces the largest practical gains in supported titles. The Gen4 drives here are compatible with the API but do not include the same firmware optimizations, so the measurable benefit in actual gameplay on Gen4 hardware is more modest and depends heavily on the specific game's implementation.
Which drive is the best choice for a gaming laptop upgrade?
For a gaming laptop, the WD_Black SN7100 is my first recommendation. Its single-sided layout, low thermal output, and strong everyday performance make it the safest fit for the narrow M.2 bays and limited cooling found in most gaming laptops. The Lexar NM790 is also single-sided and works equally well in that context. The Crucial T710 is the only Gen5 drive worth considering in a laptop upgrade, but only if the board has a confirmed Gen5 slot with adequate thermal coverage - on many gaming laptops that slot operates at Gen4 speeds regardless, which makes the Gen4 drives the more practical and economical choice.
Choosing the Right SSD for Your PC
Three use cases, five drives. Most PC upgrades land in Gen4 territory, and the WD_Black SN7100 covers that ground better than anything else here - new-generation NAND, minimal heat, strong random IOPS, and a single-sided design that fits every platform from a desktop to a PS5. When the workload shifts toward sustained writes and OS-level responsiveness under pressure, the Samsung 990 PRO is where I land - the DRAM cache and Magician software earn their keep over months of daily use, not just on launch day.
Storage budget tighter than the premium Gen4 options? The Lexar NM790 is where the value math is cleanest - 1,500 TBW, up to 4TB, and sequential speeds that lose nothing against the leaders in real use. Step up to Gen5 and the Crucial T710 is the first drive in that category I trust in a laptop as much as a desktop - lower thermals than any E26-based rival and DirectStorage firmware that actually works. The SABRENT Rocket 5 is the desktop-only answer for builders who have their M.2 cooling handled and want the Phison E26's full output without compromise. Slot, workload, budget - answer those three and the right drive here is obvious.
