8K random read and write speed is a metric that is not tested for consumer use, but for enterprise environments this is an important aspect of performance. With several different workloads relying heavily upon 8K performance, we include this as a standard with each evaluation. Many of our Server Emulations below will also test 8K performance with various mixed read/write workloads.

 

The average 8K random read speed of the HGST array comes in at 530,377 IOPS at QD256, while the Micron array peaks at 479,303 IOPS.

The 8K random write results from the RAID 5 arrays closely mirrors the results we received with the 4K random write workloads, with the peak occurring at QD64 for the both arrays.
