PCPer File Copy Test

Our custom PCPer-FC test does some fairly simple file creation and copy routines in order to test the storage system for speed.  The script creates a set of files of varying sizes, times the creation process, then copies the same files to another partition on the same hard drive and times the copy process as well.  There are four file patterns that we used to try and find any strong or weak points in the hardware: 10 files @ 1000 MB each, 100 files @ 100 MB each, 500 files @ 10 MB each and 1000 files at 1 MB each. 

We've grouped the SSD wrk along with other high performing SSDs, and as we can see here, the whole pack offers similar performance in simple file shuffling tests. While the higher max write speeds of most other units was able to beat the wrk in file creations, the high write IOPS capabilities of the SMI controller shined through on 1MB file creation, where the wrk was able to beat most of the pack and nearly catch the Samsung 850 Pro.
