when its not yours your spending who cares... is often a attitude see
us government for best examples. 2 swapping the device is not the
problem its initialing the critter. ie bios must know about it or it no
workie.. also scsi is super mystical hardware.. how ever i do think
they ride their name sake a lil too much which i hope changes soon
before they go the way of novell and crapples. almost antiques but
still have their uses. (no flames plz not busting ether's chops just
stating main stream opinion)
i did a little searching and found
1) no one wants to sell desktop drives @ 10k rpm those are enterprise
things.
2) werderndigital sata 72g enterprise 10k drive that can do 4.5 ms
access is 200 80g 7.2k retale is 88. btw seagate 73g 10k scsi drive
is 120 so go figure
3) most drives available != scsi are retale and reasonable priced if it
has good access times they want near scsi prices or worse
