IOMeter 4K Throughput and Latency
Starting off, we see around 150 IOPS at QD1 moving up to 220 at QD2. QD4 expands further to 310 IOPS, and at QD8, we reach 400 IOPS. In the end, we see near 600 IOPS for the 10TB Red just behind the IronWolf 10TB.
Write IOPS is a little different, performance is quite steady instead of starting out low and ending high. For this test, we see 610 IOPS QD1 then a slight drop to 570 IOPS from QD2 through QD8. The performance then jumps back up to 610-620 IOPS and finishes strong a good 50 IOPS above the IronWolf 10TB.
Latency tells a similar story. The 10TB Red starts out around 8ms at QD1, somewhere in the middle at QD8 we see 20ms and finishing at QD32 53ms.
While write IOPS are very consistent, we see latency in a different light. At QD1, the 10TB Red sits at 4ms, moving up to QD8 that changes to 15ms and QD32 peaks at 50ms, 20ms quicker than the 8TB WD Red and 8ms over the IronWolf.
