In our experiences with news, you really don't want to RAID the spool array... it's the same idea as in a heavily loaded mail server... the smaller the disk, the more disks you have, the more spindles, the better off you are. I would personally love to have 100 2GB Barracudas in a rack, but that leads to one heckuva lot of real estate. IMHO, keep your spools away from RAID... with the introduction of U2W and 10,000 RPM drives, you can put 2 silos filled with 9 GB U2W drives, and still have it be insanely fast and large. You don't want to go above 9GB in one shot, otherwise when a drive goes, you'll lose a heckuva lot of information. Also beware of striping, as if one disk goes, you lose one large chunk of spool. And drives will go... just due to the stress of being up and running 24/7/365, usually at heavy useage. On Wed, 5 Jan 2000, Gary D.
