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.
