Dear Experts:
I have purchased DellR710 server with SAS disks of 6 nos of capacity 300gb on this i have installed VMware vsphere ESXi 5.0, for saving hard disk space installed vsphere ESXi on usb thumb drive of 8 gb capacity just befoe this entered RAID Configuration utlity and configured RAID 5 with 5 disks and one for Hot spare. but in the process of configuration i could see below as a default and left as it is .
Raid Configuration
Stripe Element size : 64kb
Read Policy:   No Read Ahead
Write Policy: Write Bck
As i do not have any idea on the above default values hence left as the above values and continued to install the vsphere ESXi5.0 on the usb thumb drive.
Please suggest me is this correct or recommended default values or to be changed. If to be changed please give me the correct values to be set.
Thanks in advance.

64KB is the right value because that is the size of the write operation that will be sent to the RAID.
