Western Digital Black2 Dual Drive Full Review - 120GB SSD + 1TB HDD in a single 2.5" package
SSD Tests - 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 140 MB/sec write speed limit really adds up when compared with most other modern SSDs, holding the Black2 significantly behind on these tests. Our test regime follows a strict partitioning scheme, meaning we couldn't test the HDD portion of the Black2 with this specific test.
