However, a hard drive is not a file system, a hard drive is a block
device. Flash memory is also a block device - you erase entire blocks at
a time, not single bytes. Thus, I suspect you'll find that pushing a
persistant object store into the block device paradigm isn't difficult.
Maybe not very efficient, but possible. Also, files on a file system are
byte oriented things, so a file system with a single file would be
another way to implement this...

Flash memory cards ofthe newer ATA style are actually emulating hard
drives. So if one would work, so would the other (ignoring power
consumption of course)
