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. 

Right at the start we are seeing oddities. Out file creation tool appears to not play nicely with NVMe spec parts, as the create times are several multiples of the copy times (this is inverted, as copy should be roughly 2x create time). Looking purely at the copy times, we see some fairly impressive figures. You may note the OCZ R4 actually turned in better figures, but it's important to note that this test uses compressible data which means the R4 was only actually moving a small percentage of this data to/from the flash. We will see later on the result of other types of data on the R4.
