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.
Here we can tell the differences between the various spindle speeds, as well as platter densities. The file creation test is more sequential, while the file copy test copies files from/to the same drive. This is a mostly single-threaded test (QD=1), so we see minimal negative impact on the 6TB Red's performance.
