Appendix F

Selecting the Best RAID Level

99

Drive segment size is limited to the size of the smallest disk drive in the array. For
example, three 250 GB disk drives and three 400 GB disk drives comprise two equal-
sized RAID 5 arrays with 500 GB of stored data and 250 GB of parity data. The RAID
50 array can therefore contain 1000 GB (2 x 500 GB) of stored data and 500 GB of
parity data.

FIGURE F-7

RAID 50 Arrays

In this example, P represents the distributed parity data.
