Asus Adol PM310: a dual-port SSD flash drive with one big caveat
Asus has quietly launched a dual-port SSD flash drive in China that bridges the gap between USB-A and USB-C devices — no adapters needed. The Adol PM310 measures 82×20×7.5mm, weighs under 43 grams, and tops out at 500MB/s sequential read over USB 3.2 Gen 2. There's no word yet on a Western release, which is the main reason to temper any excitement for now.
The hardware
The PM310's party trick is a connector on each end: USB-A on one side, USB-C on the other. Flip it to match whatever port you have. The all-metal chassis is slim enough to sit flush in most laptop ports, and a flip cap protects both connectors when the drive isn't in use. Asus lists compatibility with macOS, Android, HarmonyOS, iOS, and iPadOS — Windows support isn't mentioned in the spec sheet, though it would be surprising if it were genuinely absent.
Four capacity options are available at Chinese pricing: 128GB ($41), 256GB ($60), 512GB ($92), and 1TB ($141), per Gizmochina.
Speed and competition
That 500MB/s read figure lands in an awkward position. Kingston's DataTraveler Max reaches around 1,000MB/s, and even the SanDisk Extreme Pro Dual — an established dual-connector option already sold in the UK and US — sustains roughly 360MB/s in real-world use. The PM310 beats flash drives handily on paper but doesn't quite reach full external-SSD territory, and the dual-port format is already covered by well-reviewed rivals, according to Everything USB.
Write speeds and sustained thermal performance aren't disclosed, which makes direct comparisons difficult.
Availability
The PM310 is China-only for now. No UK or US retail listings, pre-orders, or official launch timeline have been announced. At $92 for 512GB, pricing sits above standard USB 3.2 thumb drives but below most portable SSDs — a positioning that could make sense if Asus brings the drive West at a competitive price. For the moment, the Kingston and SanDisk alternatives are the more practical options for anyone shopping today.
