Tim, The 9125 is a simple controller without a internal processor. The 9123 contains an internal processor to enhance RAID 0/1 operations. If you are testing in a JBOD configuration you will not take advantage of the 9123 internal processor. The internal processor can result in lower performance than the 9125. However if you configure the drives in a RAID configuration using the 9123 RAID utility you should see better performance than with 9125. -----Original Message----- From: Tim Small [mailto:tim@xxxxxxxxxxx] Sent: Thursday, July 07, 2011 1:39 PM To: Tejun Heo;
