13. Change the virtual drive options from the defaults listed on the
screen as needed.
Here are brief explanations of the virtual drive options:
•
RAID Level: The drop-down menu lists the possible RAID levels for
the virtual drive. Select RAID 50.
•
Stripe Size: The stripe size specifies the length of the data
segments that the RAID controller writes across multiple drives, not
including parity drives. For example, consider a stripe that contains
64 KB of drive space and has 16 KB of data residing on each drive
in the stripe. In this case, the stripe size is 64 KB and the strip size
is 16 KB. You can set the stripe size to 8, 16, 32, 64, 128, 256, 512,
and 1024 Kbytes. A larger stripe size produces higher read
performance. If your computer regularly performs random read
requests, choose a smaller stripe size. The default is 64 Kbytes.

Access Policy: Select the type of data access that is allowed for this
virtual drive:
