I intend to store my VHDs on the Perc 5/i's array, but I may convert it to a RAID10 or a RAID50 (does the 5/i support 50?)
Should I replace my Perc 5/i with a Perc 6/i? I'm seeing them on ebay for $90 and that sounds reasonable to me. I'm used to native LSI cards now (my OpenIndiana box runs a pair of LSI cards linked to backplanes, feels all professional). Is there a cheap alternative?
EDIT: I bought a Perc 6/i because screw it :3

I refuse to do a RAID5 with consumer SATA HDDs and only have them in SAS storage. In my research I've seen too many problems unless you use the right HDDs with RAID5, whereas with a RAID10 I've seen far fewer problems reported. Besides, in a RAID5 all HDDs must be read from to repair an array vs a single disk.
Look up Unrecoverable Bit Errors with RAID5 vs RAID10. RAID10 has virtually 0 because of the mirrored disks. You lose half capacity, but I can live with that for more reliability.
This massive topic has much more information than I can give regarding what is right for you.
