Are you serious?
I high end 15000RPM enterprise grade drive such as the Seagate
Cheetah® 15K.6 Hard Drives only deliver 164MB/sec.
The SATA Bus might be able to deliver 300MB/s, but an individual drive
would be around 80MB/s unless it is really expensive.
(or was that yesterday? I'm having trouble keeping up with the pace
of improvement :-)
