I think I had the super cheap ones.
I had the worst luck with them, I would lose crap like a week after I saved it.
I then devised a "password system" (more like a hidden file system) to protect my files by creating 27 folders in the disk, one for each letter of the alphabet, then 27 folders inside each of those folders for each letter and then my homework inside one of those 729 or so folders and memorizing the combination, and then realizing those empty folders alone used up like 75% of it's storage capacity so I couldn't save my homework except in maybe a txt file.
