Just as another note for those searching the archives, I buy nearly only Dell servers (1850's and 2850's these days), and I typically do RAID1 in them, and occasionally RAID5. They are plenty fast to support the RAID1 and RAID5 with the local disks, but any real high performance data storage I connect via Fibre channel array built as a 16 disk RAID0+1 (or RAID10 depending who you ask). Changing out dead drives (or even live ones) has never been an issue.
