Stripe Size
This parameter sets the size of the stripe written to each disk in a RAID 0, 1, 1+0, 3, and 5
Volume Set. You can set the Stripe Size to 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or 128 KB.
A larger Stripe Size produces better read performance, especially if the host server does
mostly sequential reads. However, if you are sure that the host server does random
reads more often, select a small Stripe Size.
NOTE: Stripe Size in RAID level 3 can’t be modified.
