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.
Our file creation test rubs some of the SandForce optimizations the wrong way. In practice, the OCZ-tweaked Vertex 3 performs better than the base firmware present on the Corsair Force GT, yet those tweaks cause the Vertex to score lower when creating a large batch of 100MB files. The 520 spiked a bit here, suggesting it is tweaked, yet those optimizations haven’t hit it as negatively in these areas. Not perfect, but a good sign so far.
File copies were in line with other SandForce units.
