RAID 5 is well suited for random access to data in small blocks. Most data transfers, reads, or
writes, involve only one disk and hence operations can be performed in parallel and provide a
higher throughput. In addition to this efficiency for random transaction operations, the RAID 5
implementation of the DS6000 is able to work in a
strip write style when processing
sequential operations for maximum sequential throughput.
2.8.3 RAID 10 array
The other possible RAID implementation in a DS6000 is RAID 10 (also known as RAID 1+0).
A RAID 10 array consists of a set of disks for
user data and their mirrors ...
