It might sound strange, but the Blaustahl USB storage device by Machdyne boasts only 8KB of storage. In 2024, when we’re used to gigabytes (GB) of storage on flash drives (also known as pen drives), 8KB seems negligible. We commonly buy drives with capacities of 16GB, 32GB, and even 1TB.

However, the Blaustahl offers something most other drives don’t: a tiny 8KB USB Drive with huge longevity. While regular flash drives typically last up to 10 years, the Blaustahl can potentially retain data for over 200 years!

Features of Blaustahl USB storage device

The Blaustahl USB storage device made by Machdyne has 8KB of FRAM (Ferroelectric RAM), incorporated with a Raspberry Pi RP2040 microcontroller. This combination allows for various secure storage applications, especially for data requiring minimal space. Its has an interesting features of long-term storage potentially with a lifespan of 95 years at 55°C (131°F), and over 200 years at 35°C (95°F).

The Blaustahl flash drive use FRAM technology, known for its:

  • Ultra-low power consumption
  • Rapid write speeds
  • Extremely high write endurance (one billion read/write cycles)

It also includes 4MB of NOR flash for firmware and a USB Type-A male port for connection. This means it works on most operating systems without needing additional drivers.

FRAM vs. Other Flash Technologies

Again, FRAM (Ferroelectric RAM) is RAM technology which has features like ultra-low power consumption, rapid write speeds, and high write endurance (lifespan exceeding 95 years at 55°C and 200 years at 35°C). This surpasses NOR flash and NAND flash, which typically last only 10 to 20 years under similar conditions.

EEPROM flash is similar to FRAM in storing small data amounts (often used in smart cards). However, EEPROM offers slower write times and lower write cycles compared to FRAM.

What Can You Store on 8KB?

Now the question is what can you store with such a tiny amount of storage? However, it’s suitable for storing a few pages of text depending on the formatting. The drive even has a built-in text editor accessible through serial communication programs like PuTTY and Tera Term.

Additionally, other potential uses for the Blaustahl’s secure storage, you can store Passwords, Cryptocurrency keys, Notes, Geocaching data.

Pricing and Availability

The Blaustahl is priced at €29.95 (approximately Rs. 2,709). You can purchase it directly from the Machdyne website.


The Blaustahl USB drive may have a tiny storage capacity, but it offers exceptional long lifespan. If you need to securely store data for decades or even centuries, this unique drive could be the perfect solution. It’s ideal for passwords and other confidential text information.
