there are 2 different versions, one which you can delete manually, you could use it for harddrives of processors. the other one will delete the information stored after reading it. i think you could use it for gpu's, like store the information of the picture it have to show next. its my first working electronic thing, so i would like to hear how it is, and how i could improve it. EDIT: this is now version 2, its half as big as before.
did you know: a kilobyte is not actually 1000 bytes. because there are 8 bits not 10 to a byte, 1 kilobyte is 2^10 bits, or 1024 bits. MB=2^20, gigabyte = 2^30, terabyte = 2^40
