Appendix B: Selecting the Best RAID Level ● 157
RAID 10 Logical Drives
A RAID 10 logical drive is built from two or more equal-sized RAID 1 logical drives. Data in a
RAID 10 logical drive is both striped and mirrored. Mirroring provides data protection, and
striping improves performance.
Drive segment size is limited to the size of the smallest disk drive in the logical drive. For
instance, a logical drive with two 250 GB disk drives and two 400 GB disk drives can create two
mirrored drive segments of 250 GB, for a total of 500 GB for the logical drive, as shown in this
figure.
