technology and computing databasesHow many drives do you need for RAID 1?
In respect to this, how many drives do you need for RAID?
The minimum number of drives required for RAID 10 isfour. RAID 10 disk drives are a combination ofRAID 1 and RAID 0, the step of which is to create anumber of RAID 1 volumes by mirroring two drivestogether (RAID 1).
Also question is, can RAID 1 have more than 2 drives?
1: He says that its impossible to have RAID1with more than 2 disks. "In RAID 1 (mirroring withoutparity or striping), data is written identically to multipledisks (a "mirrored set"). While any number of disksmay be used, many implementations deal with only2."
The minimum number of disks in a RAID5 set is three (two for data and one for parity). The maximumnumber of drives in a RAID 5 set is in theoryunlimited, although your storage array is likely to have built-inlimits. However, RAID 5 only protects against a singledrive failure.
