4k Random Read/Write
Each QD for every parameter tested includes 300 data points (five minutes of one second reports) to illustrate the degree of performance variability. The line for each QD represents the average speed reported during the five-minute interval.
4k random speed measurements are an important metric when comparing drive performance as the hardest type of file access for any storage solution to master is small-file random. One of the most sought-after performance specifications, 4k random performance, is a heavily marketed figure.
The Savvio 15K.3 trails the SSHD very closely at lower queue depths, but it levels off at 543 IOPS at QD256. The Enterprise Turbo SSHD delivers 608 IOPS.
The Enterprise Turbo SSHD really opens the gap with random write activity, taking quite the lead with 452 IOPS, while the 15K.3 delivers 428 IOPS at QD256. The 15K.3 manages easily to outstrip its 10k and 7,200 RPM brethren.
Our write percentage testing illustrates the varying performance of each solution with mixed workloads. The 100 percent column to the right is a pure write workload of the 4k file size, and 0 percent represents a pure 4k read workload.
The SSHD again leads the pack, but the 15K.3 holds its own with solid performance as we mix in heavier write activity.
We record the power consumption measurements during our test run at QD256.
The 7,200 RPM Enterprise Capacity ES.3 brings a much higher operating voltage along with its 4TB of capacity, while the 2.5-inch drives sip power below 7 watts. The 15K.3 in particular is stingy with a draw of only 6.49 watts.
We generate IOPS to Watts measurements from data recorded during our test. The 15K.3 delivers an outstanding 81 read IOPS per Watt, and its slightly lower power consumption allows it to eke out a win over the SSHD in write efficiency at 101 IOPS per Watt.
