A very important part of overall system responsiveness is down to hard drive performance. We start off with CrystalDiskMark 3.0 x64 which is a great test program for hard drive performance.
The 7,200 rpm drive is a decent performer, averaging over 100 MB/s in both sequential read and write tests. This is a clear improvement over the sluggish 5,400 rpm drive which was used in the lower priced CX640.
