Thanks. > Greg Rowe | > U S West - Interact Services | INTERNET greg@uswest.net The answers to your questions depend on which RAID level you are thinking about. IMHO RAID3/5 is only useful if you are short on money. The write performance penalty and the money to overcome it are better spent on more drives to build a simple mirroring system. Especially on small (15-20 gig) News filesystems. On the other hand, RAID3/5 may have some benefit for truly large installations. mirroring is also sometimes called RAID1. -- Brian Litzinger Powered by FreeBSD <brian@mediacity.com> http[s]://www.mpress.com
