Isn't precisely there where Flash disks would have *the* big advantage?? I mean, access time is severely held down by the *mechanical* movement of the heads to the right cylinder on the disk --- that's a brutally large amount of time compared to anything else happening on the computer (well, floppy disks aside, and things like trying-to-break-128-bit-encryption aside :-)). Or are these Flash disks so slow that they compare to the HD's latency figures? Carlos --
