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 Toshiba PX02SMF080 comes in at 88,120 IOPS at QD256. The Optimus manages an average of 74,240 IOPS at QD256, but peaks at 80,000 IOPS at QD64.

The average 8K random write speed of the Toshiba is 15,715 IOPS at QD256. The wide performance variability again penalizes the average, while the Optimus delivers an average of 23,736 IOPS at QD256.

The Toshiba PX02SMF080 delivers great performance that is above the Optimus as we mix in more writes, until the heavy 90 and 100% write workloads.

The Toshiba has a large percentage of its 8K write activity, 37.15%, land in the range of 20-40ms. 11.34% of I/O falls into the 10-20ms range, and 12.99% lands at 6-8ms. This latency variation reflects the results in the 8k write performance testing. The entire latency range spans from .1-.2ms to 60-80ms.

ABOUT THE AUTHOR - Paul Alcorn

The quest for benchmark world records led Paul further and further down the overclocking rabbit hole. SSDs and RAID controllers were a big part of that equation, allowing him to push performance to the bleeding edge. Finding the fastest and most extreme storage solutions led to experience with a myriad of high-end enterprise devices. Soon testing SSDs and Enterprise RAID controllers at the limits of their performance became Paul's real passion, one that is carried out through writing articles and reviews.
