$6,400 for 256 MB: Machdyne's FERRIT USB Drive Promises 200-Year Data Storage
If you've ever worried that your USB drive might quietly corrupt a critical file a decade from now, Machdyne has an answer — though it's an expensive one. The German hardware startup has unveiled FERRIT, a modular USB storage device built on ferroelectric RAM (F-RAM) instead of conventional NAND flash. The headline claim: data retention of up to 200 years at room temperature. The headline cost: around $6,400 for the maximum 256 MB configuration.
The technology
Standard NAND flash stores data as electrical charge in floating-gate transistors. That charge leaks over time — typically within 10 to 20 years under normal conditions. F-RAM works differently, encoding data in a ferroelectric crystal layer that doesn't bleed charge the same way. The result, per CNX Software, is a theoretical retention life of 200 years and endurance of up to 100 trillion read/write cycles — figures that dwarf anything consumer flash can offer.
F-RAM is also highly resistant to ionizing radiation, which is why it already sees use in aerospace and military hardware. FERRIT is explicitly aimed at those same markets, along with anyone who needs ultra-reliable storage of cryptographic keys, technical blueprints, or other documents where losing data is not an option.
The hardware
FERRIT is built around a Raspberry Pi RP2040 microcontroller and connects via USB-C. The operating system sees it as a standard removable drive — no drivers required. The base FERRIT-16 board holds eight 1 MB F-RAM chips. Additional FERRIT-M8 expansion modules can be stacked on both sides to push capacity up to 256 MB.
That figure looks laughable by modern consumer standards, but 256 MB is more than enough for text-based documentation, encryption keys, and firmware archives — the exact use cases Machdyne targets.
The price
The $6,400 figure comes from chip costs alone: Infineon (formerly Cypress) F-RAM modules at roughly $25 each, multiplied by the 256 chips needed for full capacity, according to CNX Software. F-RAM has never been a mass-market product, and that premium is unlikely to shrink soon.
Machdyne doesn't publish a fixed retail price — the Machdyne official page asks potential buyers to propose their own budget, since actual build costs depend on current component pricing. There is no confirmed availability in the US or UK through any retail channel.
The competition
For long-term archival on a tighter budget, alternatives exist. M-DISC optical media claims 1,000-year retention at around $5–15 per disc. LTO magnetic tape offers roughly 30 years of retention at enterprise scale. Neither matches F-RAM's write endurance or radiation resistance, but both are vastly cheaper per gigabyte.
The hardware design is fully open-source on GitHub, with KiCad schematics, PCB layouts, and C firmware available under a free license — so technically inclined organizations could build their own.
