Western Digital Caviar Green 3TB Review
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.
The included HBA throws its first curve ball at us. File copy performance is in line with the RE4-GP, which is actually very good. File creation hit a wall, as the HBA caching interfered with the method we use to create the files. Without that conflict, file creation performance would have been on-par with the RE4-GP as well.
