Crystal DiskMark / PCMark 7
Crystal DiskMark Crystal DiskMark is designed to quickly test the performance of your hard drives. Currently, the program allows to measure sequential and random read/write speeds; and allows you to set the number of tests iterations to run. We left the number of tests at 5 and size at 100MB.
For the most part these results are very good. The moderate reduction in sequential read and write performance is neither here nor there as this is still a fast drive. With that being, said the small file performance of the Black Edition 4TB is a tad disappointing. It certainly is greatly improved over past generations of Western Digital Black drives, but it is lower than the 4TB RE even at single queue depths.
PCMark 7 While there are numerous suites of tests that make up PCMark 7, only one is pertinent: the HDD Suite. The HDD Suite consists of numerous tests that try and replicate real world drive usage. Everything from how long a simulated virus scan takes to complete, to MS Vista start up time to game load time is tested in these core tests; however we do not consider this anything other than just another suite of synthetic tests. For this reason, while each test is scored individually we have opted to include only the overall score.
A score of 2301 – or 16 less than the 4TB RE – was not all that unexpected. This drive has been heavily tweaked for a more balanced approach to performance vs. noise. This in turn does make it a touch slower than it otherwise could be.
