Well, stay away from the Seagate drives.  They are pure crap.  They quote
their access times a little funny.  Like claiming that their average seek
time is 28 ms on the 4096 when the track to track time is 8 or 9 ms !  Any
good drive will have a voice coil actuator that can deliver a track to track
time below 6 ms. 
	
There are several manufacturers who make good, fast, drives.  These include
MAXTOR, CDC, PRIAM and some more that escape my memory now.  It is very 
important not to underestimate the amount of time spent waiting for a slow
disk drive.  There is no point in running UNIX on a fast processor just to
slow it down with a piggy drive.

Hope this helps...
