4K Random Read/Write
We precondition the Micron P320h with a heavy 4K random write workload for 18,000 seconds, or five hours. Every second we are receiving reports on several parameters of the workload performance. We then plot this data to illustrate the drives' descent into steady state. Each round is ten minutes in duration.
This preconditioning slope of performance happens very few times in the lifetime of the device, and we present these test results only to confirm the attainment of steady state convergence.
Each QD for each parameter tested includes many data points to illustrate the degree of performance variability. Even though there is a limit of 256QD per volume imposed by the Windows Server operating system we tested up to a QD of 512 to measure any differences gained by the coalescing settings.
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 P320h tops out at 785,000 IOPS in our testing. There is a clear distribution of the I/O in the higher QD between 600,000 and 785,000 IOPS. This may indicate some type of internal QOS functionality inside the Micron/IDT controller, or result from the command coalescence that allows more I/O to be forced through per interrupt.
The 4k random write speeds top out at 225,000 IOPS. There is very little variability in the write speeds offered by the P320h. The write performance overall is very consistent.
