Hi,
I'm presently running a raid 5 with 3 drives. If two of the three
drives fail, then I would have to re-install the OS and restore from
backup. If I use 4 drives for a Raid 5, would I not have to restore
the OS until three of the 4 drives failed? Would it be 4 of 5 drives
if I chose to have a Raid 5 using 5 drives.
What I'm thinking is that the possibilities of more then two drives
failing at once is slim but if that happens I could still keep my OS
intact if I used a Raid 5 of 4 drives or more.
Thanks

In addition to the other replies - if you've got a spare bay & your card
supports it, get another identical drive & configure it as a hotspare. This
will help you if *two* drives fail - and yes, that can happen. It will also
keep your disks from running in degraded mode if you have a single drive
fail.
