Do drives have to be exactly the same size for RAID 1?
The RAID option is greyed out—some research says that the drives need to be the same size, but do they have to be exactly the same size (to the byte) or is there some leeway (maybe a percentage)?
I have two 1TB drives, different manufacturers. One is 953980 Mb and the other is 953740 Mb, so both claim to be 1TB but are 240mb different.
Server specs are:
- Server Dell PowerEdge T310
- Running Windows 2008, 64bit
- Raid Controller Dell SAS 6/iR Adaptor
