and press the Enter key
to confirm. This parameter specifies the size of the
stripes written to each disk in a RAID 0, 1, 10(1E), 5 or 6 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 provides better read performance,
especially when the computer performs
mostly sequential reads. However, if the computer performs random read
requests more often, choose a smaller stripe size.
