This USB flash drive can only store 8KB of data, but will last you 200 years | Tom's Hardware
NAND flash memory , which is used in general USB memory, SSDs, memory cards, etc., can be made large capacity at low cost, but there is a limit to the number of times it can be rewritten, and the data retention period is said to be relatively short at 16 to 20 years. In addition, NOR flash memory , which is used in routers, printers, and built-in storage of digital cameras, can only retain data for a maximum of 20 years in a 55 degree environment. Of course, once the data retention period has expired, the stored data may be lost. Furthermore, EEPROM can retain data for 100 to 200 years at 55 degrees, but the write time is longer and the upper limit on the number of writes is relatively low.
On the other hand, non-volatile memory called ferroelectric random access memory (FeRAM) is superior to conventional flash memory in terms of high-speed writing, high rewrite count, and low power consumption. The USB memory that uses this FeRAM is the 'Blaustahl Storage Device.'
The Blaustahl Storage Device is equipped with 8KB of FeRAM, which, unlike EEPROM or NOR flash memory, is capable of minimizing power consumption while achieving high-speed writing and high durability capable of withstanding up to 10 billion read/write cycles.
According to Machdyne, the Blaustahl Storage Device with FeRAM can retain data for more than 200 years at 35°C.
The Blaustahl Storage Device has a capacity of just 8KB, so it can only store about 8,000 characters, or the equivalent of four pages of manuscript paper. However, Machdyne lists a number of possible use cases, including storing passwords, cryptocurrency private keys, memo lists, geocaching data storage, time capsules, and FRAM development.
The Blaustahl Storage Device also includes
Additionally, it has a built-in text editor that can be accessed from any serial communications program that supports VT100 emulation, such as PuTTY or TeraTerm .
Additionally, Machdyne reports that upcoming firmware updates will add encryption capabilities that will further enhance the security of the device.
The price of the Blaustahl Storage Device is 29.95 euros (about 5075 yen). Machdyne has published the circuit diagrams, blueprints and firmware of the Blaustahl Storage Device on GitHub, so users can modify the device to suit their needs.
