any difference seen in using 15,000RPM scsi drives versus using 10,000RPM scsi drives.

i know using more smaller drives rather than one large drive is better, based on more read/write

currentlt looking to replace our existing BM proxy/cache server with a new one during the summer..

single 3GHz proc w/1MB cache (turning of HT)
2 GB ram for proxy/cache/surfcontrol
minimum 2 scsi drives with at most 18GB space each, probably not use all
(looking for 9GB drives and to use all space on each for cache)
