Sorry, I was rushing out and was too terse :(
I meant _hardware_ raid (and I really meant, cheap, on-the-motherboard
RAID) is a waste of time :)
Proper hardware raid is probably overkill but hey, let he who is without
sin...
BTW that ref is : http://linux.yyz.us/sata/faq-sata-raid.html
Instead you should use the linux raid subsystem (md devices)
see: http://www.mythtv.info/moin.cgi/AdministrationSoftware_2fLvmRaid
I actually run a 1.2 TB raid 5 system with 6x250GB sata disks (and a
250Gb spare too!)
*when* (not if) one of them fails (again) the hot spare kicks in and I
end up not losing a single show.
Not only that, I'm covered in case another one fails whilst I'm waiting
for the RMA process (as happened once!)

totally agree :)

Which is why I run what I do...
