Server workloads rely heavily upon 8k performance, and we include this as a standard with each evaluation. Many of our server workloads also test 8k performance with various mixed read/write workloads.

 

The average 8k random read speed of the Enterprise Performance 15K v4 is 531 IOPS at QD256, and the Savvio 15K.3 takes a slight lead with 535 IOPS. The Toshiba 15K comes in third with 522 IOPS at QD256.

The Enterprise Performance 15K v4 runs neck and neck with the previous-generation Savvio 15K.3.
