For some reason I am not able to post into News section, so I will place it on second most suitable place - here.
Maybe some mod can kindly move it to HW news section ?

WD is now introducing two families of WD-branded consumer SSDs, each derived from existing SanDisk product lines.
The WD Blue SSD is based on the SanDisk X400 SATA SSD with minimal hardware changes but has modified firmware and different usable capacities. Like the X400, the WD Blue is available as either a 2.5" or M.2 drive and uses SanDisk 15nm TLC NAND with the Marvell 88SS1074 controller.
The WD Green SSD is an entry-level product line with limited capacity options. Based on the SanDisk SSD Plus, it uses a Silicon Motion controller in a DRAM-less configuration with SanDisk 15nm TLC NAND.

And AT already made a review of 1TB variant of Blue. HERE
The WD Blue follows in the footsteps of the SanDisk X400 and doesn't break any new ground. The hardware is essentially identical, but the firmware has been re-tuned. The WD Blue trades some capacity for an increased write endurance rating that is above average for a mainstream SATA SSD. The extra overprovisioning allows for improved sustained random write performance, one of the few benchmarks where the X400 was not the fastest planar TLC drive. Unfortunately, the WD Blue is slower than the X400 on most other tests and is not able to secure a claim to being the fastest budget SSD, though it does offer decent well-rounded performance with no major shortcomings. In spite of the increased endurance rating, the WD Blue only comes with a three year warranty compared to the five year warranty offered on the X400.

Budget SSD with not-above-usual speeds and TLC. I think I will pass.
