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.
Wow! The Red beat out all but the VelociRaptor in file creation. This is surely due to increased platter density (all Red models are 1TB / platter). That higher density enables it to fly past even the older 7200RPM RE4 and Black drives.
During this test I immediately noticed something – no seek noise. None. I had to nearly lay my head on the drive to hear only the slightest scratchiness of the head pack actuator. No rattles, ticks, or other sounds you'd hear from the other drives. The Red is clearly tuned for dead-silent NAS operation.
Those slower seeks likely added up a bit in file copies, letting the Black get a slight leg up along with the VR. The Red still beat the rest of the pack though.
