Among a number of bulletins right now, Western Digital is introducing a brand new extra reasonably priced PCIe Gen4 SSD beneath their gaming-oriented WD Black model (styled WD_BLACK). The new WD Black SN750 SE isn’t just a refresh of their present SN750 however as an alternative seems to be a wholly new and totally different drive. The SN750 SE brings PCIe Gen4 assist however in different respects appears to be a downgrade in comparison with the SN750, and seems to have extra in widespread with the WD Blue SN550. Based on the images and the few efficiency specs which were disclosed up to now, the SN750 SE appears to be like like a 4-channel DRAMless NVMe SSD, with respectable sequential learn throughput however lowered sequential write throughput in comparison with the unique SN750. Random IO efficiency was not included on the info sheet—not a very good signal.
UPDATE: Our mates over at PCGamer have realized that WD is utilizing the Phison E19T DRAMless controller for this drive, and the product listings at the moment are stay with just a few extra detailed efficiency specs.

The WD Black SN750 SE is meant to be the extra reasonably priced Gen4 various to their flagship SN850. The smaller controller, lack of DRAM, and newer NAND flash all mix to make the SN750 SE a considerably lower-power drive than its nominal predecessor, although the extra fascinating comparability could be towards the WD Blue SN550. Write endurance scores for the SN750 SE match the unique SN750, however the 2TB mannequin has gone lacking. Pricing begins at $54.99 for the 250GB mannequin, the midpoint between the WD Blue line and the prevailing WD Black merchandise. The WD Black SN750 SE is now obtainable for pre-order direct from Western Digital, and will likely be obtainable by means of retailers and system integrators this summer time.
This is not the primary time that Western Digital has made a large number of the naming of their WD Black SSDs. The first era in 2017 was merely the WD Black PCIe SSD. The subsequent yr, they launched one other WD Black SSD that was an enormous improve: switching from a Marvell controller to their new in-house controller, and from 15nm planar TLC to 64L 3D TLC NAND flash reminiscence—however the branding was confusingly related, and one of the simplest ways to inform which era you have been shopping for was to examine if the marketed capability was 256GB/512GB (outdated) or 250GB/500GB/1TB (new). In 2018 Western Digital made essentially the most minor of refreshes by releasing the WD Black SN750; essentially the most important change over its predecessor was the addition of an unambiguous (till now) mannequin quantity. The {hardware} was an identical and the firmware bought solely a minor replace, and a model with a heatsink was added. That SN750 has been overdue for an replace to make use of 96L as an alternative of 64L TLC, a change which Western Digital made for his or her OEM drives by changing the SN720 with the SN730. But the SN750 SE is not the straightforward NAND refresh we anticipated primarily based on its title, neither is it a real successor and improve to the SN750.
The SN750 SE ought to make for an excellent mainstream NVMe drive. Western Digital has a wonderful observe report for getting good efficiency from DRAMless NVMe SSDs, and it will in all probability be sufficient to leapfrog the latest Samsung 980. But utilizing a reputation that is so just like such a unique product is a critical…
