We start with the database 80/20 workload similar to OLTP testing via the SNIA standards. The WD Gold starts at 200 IOPS QD1 and gets a nice bump in performance to QD16 where we see a touch under 500 IOPS.
File Server peaks at 500 IOPS at QD32 for the WD Gold, slightly behind the WD Red.
Moving to Email Server, the Gold jumps out of the gate a touch under 250 IOPS at QD1 and ends testing at 450 IOPS at QD32.
Web Server shares similar performance to File Server, starting near 150 IOPS at QD1 and ending at 520 IOPS at QD32.
Workstation starts a touch under 200 IOPS for the Gold moving to 250 IOPS at QD2 and 320 IOPS at QD4. QD8 lands at 400 IOPS while QD16 touches 500 IOPS.
Our custom power testing samples each drive for a period of three minutes, across each workload. In order to offer more granularity, we sample the power in one-second intervals.
Taking a look at power consumption, I was surprised to see my results so close to WD specifications.
Random read and write hovered between 6.3 and 7 watts while sequential workloads stuck close to 7 to 7.2 watts.
