However, as with any flash storage, data loss from bit leaking due to prolonged lack of electrical power and the possibility of spontaneous controller failure due to poor manufacturing could make it unsuitable for long-term archival of data. Additionally, they are less vulnerable to electromagnetic interference than floppy disks, and are unharmed by surface scratches (unlike CDs). Compared with floppy disks or CDs, they are smaller, faster, have significantly more capacity, and are more durable due to a lack of moving parts. Some allow up to 100,000 write/erase cycles, depending on the exact type of memory chip used, and are thought to physically last between 10 and 100 years under normal circumstances ( shelf storage time ).Ĭommon uses of USB flash drives are for storage, supplementary back-ups, and transferring of computer files. As of 2018, 2 TB flash drives were the largest available in terms of storage capacity. As of March 2016, flash drives with anywhere from 8 to 256 gigabytes (GB ) were frequently sold, while 512 GB and 1 terabyte (TB ) units were less frequent. Since first appearing on the market in late 2000, as with virtually all other computer memory devices, storage capacities have risen while prices have dropped.

It is typically removable, rewritable and much smaller than an optical disc.

He apparently couldn’t track down the same switch, but the four red Grayhill 76 Series switches arguably make it a bit clearer when entering in your bytes.Įach of the individual DIP switches are connected to one of the GPIO pins of the 8-bit EFM8UB2 microcontroller, and the code simply reads the state of each pin in order and saves the binary results in a variable to put together the “file” it presents to the OS when plugged in. Reading out the first byte from the DIP switches.Īs explained in a Twitter thread, was inspired to create this gadget after another user posted a picture of a 32 position DIP switch with a caption that said it was a “ One Tetrabyte SSD” back in December. Even better, you don’t need a computer to write to it: the 32 DIP switches let you key in the content on the fly, bit-by-bit. As in the Greek tetra, this drive can hold a massive four bytes at a time. That said, this USB-C tetrabyte drive created by might be slightly too small for our tastes. In fact they’ve gotten so large that it can feel wasteful using them for some tasks, and we occasionally find ourselves wishing we could find some modern USB drives that didn’t rival the storage capacity of our whole computer. It wasn’t so long ago that two and four gigabyte drives were considered to be on the high end, but today you can grab a 512 GB drive for less than $50 USD.

In a relatively short amount of time, the average capacity of USB flash drives has skyrocketed.
