8K Random Read/Write
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 will also test 8K performance with various mixed read/write workloads.
The Toshiba MK01GRRB/R drives perform well, with a nice linear scaling of performance in this commonly utilized file size. We can see the 8-drive configuration topping out at 3,200 IOPS on average at QD256, the 5-drive sets at 2,285 average IOPS and the 3-drive setup provides 1404 IOPS.
The 8K random write workloads exhibit much of the same characteristics of the 4K testing, with a bit of variability at the upper end. The 8-drive combination achieves average speeds of 824 IOPS at QD256, the 5 drives score 551 IOPS and the 3 drives score 450 IOPS.
