Even better, most of the good SCSI-2 drives will cache
themselves. With NetBSD, you then have caching at both the system's end
and the drive's end, which makes a caching controller almost pointless.
The memory will do much more for you on the motherboard.
The Quantum Empire series drives have 512K caches, Seagate Barracudas
have 1024K. Other drives I don't know about - good ads will list this
with other specs.
