Final Thoughts




When we reviewed the SanDisk X400, it caught us by surprise because it was the first non-Samsung SATA-based TLC SSD that delivered moderate workload performance that is compelling. We feel that moderate workload performance is the best indicator of how well a SSD will perform in an OS environment for the majority of users. Whenever a SATA based SSD delivers random performance of over 10,000 IOPS at 4K QD1 read, it is indeed something special.


Western Digital's Blue SSD is, in fact, an X400, but it is even better because WD incorporated overprovisioning. Throughout our testing, the WD Blue displayed front and center that OP does have a significant impact on overall performance. The Blue outperformed the X400 significantly with the lone exception of our Vantage testing.



We tend to view things from an enthusiast perspective, and when viewed through this lens, the Blue is definitely a better choice than the X400. However, let's take a step back from our enthusiast views and look at the Blue from a budget conscious point of view where performance is secondary to cost per gigabyte. First, let's compare the Blue to Samsung's 850 EVO. Samsung's 1TB 850 EVO outperforms the 1TB WD Blue. Both net the end-user the same amount of user-addressable capacity, but the WD Blue is about $40 cheaper. For the value shopper, the Blue is probably the better choice because it is cheaper, almost as fast and the Blue has a better endurance rating than the EVO.


Now, let's compare the Blue to the X400. The 1TB Blue costs about $30 more than the 1TB X400 while at the same time giving you 22.4GB less user-addressable capacity. Performance aside, the X400 is the better value because it still delivers compelling performance and you get more usable capacity. WD needs to keep in mind that the vast majority of those who would purchase the Blue are looking for the best value. In our opinion, WD needs to kill off the X400, lower the pricing on the Blue by 10%, and include cloning software. We believe if WD does these three things, then the Blue will become the obvious choice for the value oriented buyer.


Obviously, we would like to see the pricing of the Blue cut by around 10%, but its current pricing is still not unreasonable for the SSD experience it delivers. Western Digital's 1TB Blue delivers a true tier-one SSD experience that is sure to please, which is why it is TweakTown recommended.
