RAID 10 and 01 storage capacity Tags: NAS / RAID Storage Last response: July 21, 2010 12:10 PM in Storage Share PabloRSA July 21, 2010 10:39:34 AM Hi all Im starting to get a headach from this but correct me if im wrong. If i had 4 x 1TB drives Raid 01 would be, stripping (1TB+1TB) - mirroring (1TB)+(1TB) Raid 10 would it be Mirroring (1TB)= (1TB) - stripping (1TB)+(1TB) From what I see above Raid 01 would = 2TB capacity and it being mirrored where as Raid 10 would be 1TB capacity mirrored and a copy of the mirrored being striped only ever using 500gb. Am i correct? More about : raid storage capacity GhislainG a b G Storage July 21, 2010 11:47:50 AM Both will be 2TB. In one case you mirror two 2TB stripes; in the other case, you stripe two 1TB mirrors.
