The first test we will run through is our Workstation scenario, with an 80/20 read/write distribution utilizing 8K transfers. Here you can see the WD Red did quite well, coming to rest at a very comfortable 160 IOPS at QD256.
The second test focuses again on an 80/20 distribution, but instead a mixed workload between 512-byte and 64KB. Here to my surprise the WD Blue jumped to the top of our chart, with our newly received Red close behind. Here the Red topped out just north of 160 IOPS.
Next up we have the OLTP/Database workload, covering a 67/33 read to write ratio centered on 8K transfers. Here again, we find the WD Red performing quite well, coming in above all comparable drives, minus the surprisingly quick WD Blue.
Above, we have our average latency from IOMeter. This is centered on 4K transfers and is the average from a run of three. Here we see the WD Red ready to work, coming in at 3.19ms in our write latency testing and refusing to hold back in the read portion as well at 8.11ms.
