Micron P320h PCIe Enterprise SSD Review

8K Random Read/Write






8K random read and write speed is a metric that is not tested for consumer use, but for enterprise environments this is an important aspect of performance. With several different workloads relying heavily upon 8K performance, we include this as a standard with each evaluation. Many of our following Server Emulations will also test 8K performance with various mixed read/write workloads.


The P320h serves up 375,000 IOPS in pure 8K random read speed, with very little variability with the slightly larger file size. We also do not note the spread in read speed as we did with the 4K random read testing.




The 8K random write speed tops out at 44,000 IOPS at QD256, but raises up above that to an average of 47,000 IOPS, and even higher, at QD512. This is probably due to the more efficient coalescence settings for the P320h.
