Western Digital Blue 1TB SATA III SSD Review

TweakTown Rating: 88%Manufacturer: Western Digital



Version and / or Patch Used: 2.47


ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products. With ATTO, we are looking at maximum sequential performance with compressible data as well as the performance curve.




Compressible sequential read/write transfers max out at 563/527 MB/s. Both figures exceed WD's factory specs. Keep in mind this is our OS volume, and it is filled to 75% of its total capacity. Maximum sequential performance is achieved at 1MB transfers.


Sequential Write




Right off the bat, we notice the WD Blue delivering a better performance curve than SanDisk's X400. We feel this is due to overprovisioning present on the Blue. The 750 EVO and MX300 both ramp up faster than the Blue.


Sequential Read




The Blue is delivering the best small file performance of the bunch. The MLC-powered XTi takes the lead in the middle of the test. The Blue leads the field at the end of the test. Again, we see the Blue outperforming the X400.




Anvil Storage Utilities


Version and / or Patch Used: 1.1.0


Anvil's Storage Utilities is a storage benchmark designed to measure the storage performance of SSDs. The Standard Storage Benchmark performs a series of tests; you can run a full test or just the read or write test, or you can run a single test, i.e. 4k QD16. With Anvil's, we are focused on the total score.








Anvil's scoring typically provides us with a good indication of a drive's overall synthetic performance. Whenever we get a score of over 5,000, we take notice. The Blue delivers a very impressive score of 5,051. This is second only to Samsung's 750 EVO. The Blue even manages to outscore the MLC-powered XTi.


Comparing the Blue to the X400, we find the Blue delivering far better write performance and a far better total score. We consider 4K QD1 random read performance to be one of the best indicators of how well a drive will perform as an OS disk. We consider 10K at QD1 a milestone that very few SSDs are capable of delivering. Only the best can do it, and the Blue does it with ease.


(Anvil) Read IOPS through Queue Depth Scale




The Blue and X400 both deliver superior performance up to QD8, after which the Blue outperforms the X400. The Blue and X400 both deliver the goods at low queue depths which is what we are looking for when judging synthetic performance.


(Anvil) Write IOPS through Queue Scale




The Blue does outperform the X400 across the board. However, both are outperformed by the majority of the competing drives in our test pool.
