Hi Andrew,

I was subscribed to BYTE from shortly after it was introduced until the 
early 1990s and used to look enviously at advertisements for the 
solid-state disks (ditto the large Pinnacle-Reo MO drives!), once they 
were introduced, so I was well aware of their existence - noted some 
recently that were 90GB capacity!
None of them however were incorporated into a conventional hard-disk 
though - like a larger, slooooower on-disk-cache, though the quoted size 
of 128MB seems terribly small, especially for the Longhorn behemoth!

I am very disappointed with the access speeds of my 512MB USB2.0 
PendrivePro Flash drive, especially the write speed! Tried FAT and HPFS 
[terrible] and finally settled on JFS.
