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. 

Octane busted out the gate and promptly smacked down everyone else on the field, including even the best offerings from SandForce.

Octane did not fare as well in batch copying of larger files. Since this test copies the files to/from the drive, it forces the controller to simultaneously read and write. For drives with larger caches (like the Octane), more juggling must be done as the controller occasionally purges the RAM cache out to flash memory. Even with a large cache, performance here boils down to how that particular controller was tuned, so there is room for improvement with a bit of tweaking to those configs.
