The Western Digital Blue (1TB) SSD Review: WD Returns to SSDsby Billy Tallis on October 11, 2016 8:00 AM EST

Five months after completing its acquisition of SanDisk, Western Digital is introducing SSDs under the WD brand for the consumer market. The WD Blue is the mainstream SATA offering and is derived from the SanDisk X400. While not exactly the first Western Digital SSD in blue, the WD Blue is the beginning of a new era for the WD brand and is an acknowledgment that SSDs are now mainstream consumer products that exist alongside or displace hard drives instead of just occupying a high-end niche.
The SanDisk X400 was announced at the beginning of this year as the new flagship of SanDisk's business/OEM client SSD family. When we reviewed it in May we were pleasantly surprised to find that it raised the bar for the performance and power efficiency of planar TLC SSDs and was a credible mid-range drive, not just an entry-level budget-oriented product. The WD Blue SSD uses the same hardware platform as the SanDisk X400, but with some changes to the firmware. Most notably, the WD Blue reserves a bit more spare area and thus has capacities of 250GB, 500GB and 1000GB where the X400 has capacities of 128GB–1024GB. There are minor differences to the performance specifications and the WD Blue has only a three year warranty compared to the X400's five years. (Though still better than the two year warranty carried by the current WD Blue hard drives.)
|Western Digital WD Blue Specifications|
|Form Factor||2.5" 7mm SATA or M.2 2280 SATA|
|NAND||SanDisk 15nm TLC|
|Sequential Read||540 MB/s||545 MB/s||545 MB/s|
|Sequential Write||500 MB/s||525 MB/s||525 MB/s|
|4KB Random Read||97k IOPS||100k IOPS||100k IOPS|
|4KB Random Write||79k IOPS||80k IOPS||80k IOPS|
|Average Power||70 mW|
|Max Power||4.4 W|
|Endurance (TBW)||100 TB||200 TB||400 TB|
All capacities of the WD Blue are available in either the 2.5" SATA form factor or as M.2 2280 cards. This continues the trend of recent mainstream SATA SSDs placing M.2 on an equal footing with the 2.5" form factor.
As a result of the increased spare area, the WD Blue has a higher write endurance rating than the SanDisk X400 and one of the highest endurance ratings of any TLC SSD. It even exceeds the rating on some capacities of the Samsung 850 Pro that comes with a 10 year warranty. Western Digital is pitching the WD Blue as suitable for heavy workloads, and even if its performance falls short of the best SATA drives it should last a very long time even when subject to a write-intensive workload.
|SSD Endurance Specifications Comparison|
|WD Blue||100 TBW||200 TBW||400 TBW|
|SanDisk X400||80 TBW||160 TBW||320 TBW|
|OCZ Trion 150||60 TBW||120 TBW||240 TBW|
|OCZ VX500||148 TBW||296 TBW||592 TBW|
|Samsung 850 EVO||75 TBW||150 TBW||150 TBW|
|Samsung 850 Pro||150 TBW||300 TBW||300 TBW|
The construction of the WD Blue carries over the same metal case and plastic lid that SanDisk has been using for years. Inside our 1TB sample we find the same single-sided PCB as in the X400 and the thermal pad that covers nearly every component. The NAND is arranged in eight packages of 128GB each, while the Micron DRAM is split across two packages.
For this review the 1TB WD Blue will be compared against most of the other 1TB-class SATA drives we have tested. The current competition in the marketplace consists primarily of the preceding SanDisk X400, cheaper planar TLC SSDs such as the OCZ Trion 150, MLC SSDs that are mostly significantly more expensive, and 3D TLC SSDs such as the Samsung 850 EVO and Crucial MX300. Note that while we have already reviewed the 750GB Crucial MX300, in this review we are comparing against the 1050GB MX300 that will be covered by an upcoming review of the wider range of MX300 capacities that are now available.

Finally, HDD vendors make it back to consumer hearts, with an SSD.
Lolimaster - Wednesday, October 12, 2016 - linkThe Mushkin Reactor is still a champ if you don't wanna go for the 850Pro.
Lolimaster - Wednesday, October 12, 2016 - linkI think you only got 3-4 options for SSD's.
*Add Hynix SSD's when they sell the 1TB model.
Lolimaster - Wednesday, October 12, 2016 - link*Samsung 850Pro/EVO
2016, still no edit button...
mapesdhs - Friday, October 14, 2016 - linkSad part is we'll be saying the same thing next year.
MrGulio - Wednesday, October 12, 2016 - linkEach time I see a new SSD review it reminds me more and more what a garbage fire the BX200 is.
Bulat Ziganshin - Saturday, October 15, 2016 - linkhere in russia samsung 750 and sandisk ultra 2 are good competition too, providing prices comparable to trion 150 devices. but on american amazon they are no better than mx300
Bullwinkle J Moose - Saturday, October 15, 2016 - linkExtra large premium for the Pro???
I require a minimum of 160GB for my Boot Drives in my test Rigs so I need 250 - 256GB SSD's minimum
Lets look at the Huge Premium at Newegg for the 250/256GB EVO & Pro
Oct 15 2016
850 EVO / 250GB $99.99 OUT OF STOCK
850 Pro / 256GB $123 IN STOCK
850 EVO warranty 3 years
850 Pro warranty 10 years
850 EVO TLC Nand
850 Pro MLC Nand (40nm process)
850 EVO ???
850 Pro None
Would anyone here spend more than the difference in price between these 2 SSD's just for an extended warranty on an EVO?
The better buy is the Pro!
It also has much better compatability with various Operating Systems than PCIe / M.2 SSDs
I'm using mine for Windows XP / Windows 8.1 / Windows 10 and Linux Mint
Try running any OS that is not a DRM Spyware Platform on your precious M.2 drive
TheinsanegamerN - Monday, October 17, 2016 - linklinux mint/ubuntu/arch/ece love the 950 pro.
