Desktop Test System




IOMeter - 4K Random Performance with QD





Starting with Random read performance, we found the Archive HDD to perform just as well as the 4TB Desktop HDD and in some cases at higher queue depths a bit better. Peak performance was obtained at QD32 at 456 IOPS.




Write throughput first showed burst performance with the drive's cache allowing 3500 and 2710 IOPS in QD1 and 2 after which performance slowed to an average of 100 IOPS through the rest of testing.




Random read latency too was similar to the Desktop HDD where we initially started at 7.3Ms eventually peaking at 70 Ms at QD32.




With the cache at full speed at QD1 and 2, results were off the chart coming back into play at QD4 at 44 Ms. Peak latency was seen at QD32 at 270 Ms.
