Default Crazy idea........USB flash drives converted to IDE or SATA disks.

Can you elaborate on your technical insite?


There is often no wear-levelling on CF or usb-sticks
what I've seen in the specs. (some do have them, but not all)

This (IMO) makes the use of cheap CF/USB memory in a normal disk
configuration less optimal than a 'real' SSD drive, since blocks cannot
be remapped due to wear on the cheaper DIY version, and they will thus
break sooner.

If the disk is only written to very seldom, it is acceptable, but for
logging filesystems (NTFS,ext3 etc) I don't think would be so good to
use DIY flashdisks, if you know there is a lot of rewrites.
