Keep in mind that there are a LOT of RAID controllers out there, and yes, some of them suck royally. Especially the consumer-grade stuff intended for people to use on their home systems. I'd be willing to bet that software RAID is faster than 90% of the consumer grade RAID cards, and probably more reliable than most of them as well. Controllers make a huge difference, even in server class RAID (in my experience). There is a significant gap in performance between the good stuff and the good enough stuff. -- Bill Moran http://www.potentialtech.com http://people.collaborativefusion.com/~wmoran/ _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
