RAID 5, just because I got so many drives

Hi.  I recently bought 10 SAS 3TB drives :D  If I'm not at all concerned about the data in the array, can I do a RAID 5 config in the array?  With 6 SAS2 drives in RAID 5 config, maybe I will be able to achieve PCIe performance?  How will I be able to use parity?  I have a Dell PercH310 with LSI SAS2008, SAS2 card in IT mode, can connect up to 8 drives.

Unraid does not support any of the traditional RAID types in the array (hence it's name).

 

The closest you would get is to use the BTRFS variant in the cache pool.

Unraid is not RAID, you can never use stripping on the array, you can a raid5 cache pool or uses for example raid0 volumes as arrays devices, I have a small server where all arrays devices are two disks in raid0 (including parity).

@itimpi, thanks!

@johnnie.black, can you clarify how do to it again?  Each array is made up of 2 drives, in raid0?  What do you mean by including parity?  You mean you have 2 drives in raid0 assigned as parity?

Also note that the H310, even if flashed to RAID mode, can only create two RAID groups, you need a MegaRAID controller for more, starting with the 9240-8i and above.

That's supposed to be my next question, how many raid 0 my controller can make :-).

Thanks @Johnnie.black, there goes the project :-)
