Western Digital RE4-GP 2TB Review: Big Green Gets Meaner!
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.
This was the first test I ran on the drive. The gains in performance prompted an email to our contact at Western Digital. The RE4 took such a leap in throughput that I suspected it might have been a 3-platter drive. WD reassured me these were still 500GB platters, but that the track geometry has been further optimized for their enterprise class drives. They can get away with increased linear density of the tracks because of the tighter tolerances upheld during manufacture of these drives.
