On my work PC, I'm running a RAID 1 currently.
I have an opportunity to upgrade my system and I'm wondering what is the best setup I can use.
I have 4 available hard drives and I definitely need fault-tolerance. I heard that RAID 10 is better than RAID 5.
Which configuration should I go with?
1Well, RAID 10 is certainly the "Rolls-Royce" of RAID configruations. Guess it really boils down to a) do I really feel I need it, and b) can I afford to buy that many disks... – marc_s – 2009-07-15T16:08:12.387
c) Does my RAID adapter support RAID10? – Russ Warren – 2009-07-15T16:12:27.323
"raid5 is a bit of a waste on 4 disks" - more than that: on an array this small, it's outright dangerous ( http://en.wikipedia.org/wiki/RAID_5_write_hole et al) when compared to RAID 10.
