The big picture: Just like processing power, storage capacity is an aspect that grows with every product cycle. But one unassuming device has emerged that bucks the trend. This humble USB flash drive is making waves not for its cavernous storage capabilities, but for its remarkable longevity.
Meet the Blaustahl Storage Device, a USB flash drive that can only store 8KB of data, but boasts an incredible lifespan of over 200 years. Unlike conventional NAND flash memory found in most USB drives and SSDs, which has a relatively short data retention period of 16 to 20 years, the Blaustahl Storage Device employs a different type of non-volatile memory called ferroelectric random access memory (FeRAM).
The cutting-edge technology offers several advantages over traditional flash memory, including high-speed writing, an impressive rewrite count, and low power consumption.
At the heart of the Blaustahl Storage Device lies an 8KB (64Kbit) FeRAM. According to its manufacturer, Machdyne, this FeRAM can retain data for a staggering 200+ years at 35°C and 95 years if the temperatures are bumped up to 55°C. Additionally, it boasts an endurance of 10^12 read/write cycles at 85°C, making it virtually indestructible for most practical purposes.
While 8KB may seem like a minuscule amount of storage by today's standards, it's important to remember that this device is designed for specific use cases where data longevity is paramount. Think of it as a digital time capsule, perfect for securely storing important passwords, cryptocurrency keys, personal notes, or even geocaching data, if you're feeling adventurous.
To further enhance its security, the Blaustahl Storage Device features a built-in text editor accessible through serial communication programs like PuTTY and Tera Term. This allows users to easily manage and update their data without relying on external devices or software.
The device is powered by a Raspberry Pi RP2040 dual-core Cortex-M0+ processor running at 133MHz and boasting 264kB of SRAM. It also includes 4MB of NOR flash memory (greater than the primary storage!) for firmware. This should come in handy considering Machdyne has promised to introduce encryption capabilities in an upcoming firmware release for additional security.
And for those with a penchant for tinkering, the company has made the firmware, schematics, and enclosure design files available on GitHub, allowing users to explore and modify the device to their heart's content.
The Blaustahl Storage Device is priced at 29.95 Euros and ships from Germany.
