RAID 5 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 HGST array peaks at an average of 669,711 IOPS at QD256, while the Micron array reaches 318,811 IOPS.
Garbage collection routines are more pronounced in heavy write workloads. This leads to more variability in performance.
The HGST SSD800MH peaks at QD64 with 30,561 IOPS. The Microns top out at QD64 with 27,571 IOPS. With write activity, we note that performance actually decreases as we add in higher QD.
