Stripe Size
- specifies the size of the segments written to each disk in an array. You
can set the stripe size to either 2KB, 4KB, 8KB, 16KB, 32KB, 64KB, or 128KB. A
larger stripe size allows better performance when your system does sequential reads
often. Other set to a smaller stripe size.
Write Policy
- sets the caching method. In
Write-back
method, the controller sends
a data transfer completion signal to the host when the controller cache has received
all the data in a transaction. In
Write-through
, the controller sends a data transfer
completion signal to the host when the disk subsystem has received all the data in a
transaction. Write-through allows more data security than Write-back, but the latter
allows better performance.
