For workloads that require a lot of disk head movement relative to the amount of data moved,

SAS disk drives provide a significant performance benefit.

Random writes present additional complications beyond those involved in random reads. These

additional complications are related to Lustre locking, and the type of RAID used. Small random

writes to a RAID6 volume requires a read-modify-write sequence to update a portion of a RAID

stripe and compute a new parity block. RAID1, which does not require a read-modify-write

sequence, even for small writes, can improve performance. This is why RAID1 is recommended

for the MDS.
