Hi: Thank you for your response. I had tried to configure the first SAS HD as RAID 0 before. The RAID 0 SAS HD was also recognized as SCSI-0 device.
I think the problem is not on the size of RAID 5 HD. Thanks 2007/5/17, Olivier Nicole <[EMAIL PROTECTED]>:

As for the speed, RAID 5 is not optimized for speed but for reliability while preserving a low ratio of parity vs. data disk. If you are interested with more speed, you may have to select another RAID agregation (this morning I found http://www.acnc.com/04_01_00.html that shows good comparison for every RAID config).
