Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.
Here the WD Blue was able to achieve 556MB/s read and 511MB/s write. 4K read is very high at 43MB/s and 4K write is as well with a result of 151MB/s. This is very good to see, let’s move on and see how it performs in the rest of our synthetic tests.
The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.
In AS SSD the WD Blue hit a great score of 1174 points. Sequential read performance is nearly 520MB/s and write is a bit lower than we were expecting at just 414MB/s. 4K read and write are both very good here, however. It reached 40MB/s read and 126MB/s write. It also hit 96K IOPS read and 72K IOPS write. During the copy benchmark both the ISO and Game tests it reached high results of 445MB/s and 464MB/s respectively.
ANVIL STORAGE UTILITIES PROFESSIONAL
Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.
In Anvil Storage Utilities the WD Blue SSD achieved an overall score of nearly 5000 points. Read performance in this test was only 398MB/s, but write was back up to 481MB/s. 4K read and write are very good during this test as well. It achieved 91K IOPS read and 75K IOPS write.
