WD Black SN750 NVMe 1TB M.2. NVMe SSD (2019)
A week or two ago Western Digital announced a new WD Black NVMe M.2. SSD, the SN750 is a series in the WD Black series SSDs which now also includes a 2TB model. The entire series is PCIe 3.0 x4 NVMe SSDs based on 64-layer NAND. WD having acquired Sandisk, that NAND would be produced by them. The new SN750 SSD shares a lot od DNA to that of the 2018 model . The performance as such will be roughly similar. Interesting is the addition of a 2TB model to the existing range of a 250GB, 500GB, and 1TB model. Each volume size is available in two SKUs, as optionally you can purchase one with an EK based heatsink.
Mind you that I tagged this product review with (2019), as WD tends to reuse the naming and we don’t want to confuse you with older and/or future models.
An SSD targeted towards gaming laptops and high-end PCs, it’s thin and available in capacities of 250 GB, 500 GB and 1TB volume sizes. This SSD series offer peak read performance of up to 3,400 MB/s and a peak write speeds up to 2,800 MB/s. And gosh, that is so much faster way compared to what you can achieve with a SATA3 device. A small side note, performance will differ with different volume sizes, but smaller versions use less NAND channels and thus have slower writing. That said, whatever size you choose, the perf will be great. The random performance rated up-to 500K random read IOPS and up to 400K write for 4K IOPS. Being M.2., you do need a modern motherboard with capable NVMe supported M.2 (PCI-Expresse Gen 3.0 x4 (and not x2) connected) interface, please do check out your motherboard manufacturer for that. But ever the past year or two all Intel and AMD chipset released in the mainstream to high-end class support it very well. M2 is interesting stuff, these smaller form factors storage units are evolving from being “just as fast” as a regular SSD towards double, tripling, heck… even quadrupling that performance. It comes in a different package, M.2. The M.2 interface is so much more capable as it can deal with way more bandwidth using PCI-Express lanes. As such, M.2 solutions are intended for enthusiast class motherboards. The series M.2 SSDs are a breathtaking series of storage technology as they offer enthusiast class performance yet remain reasonable in pricing depending on NAND type.
The SSD is WDs latest iteration of their consumer-ready Non-Volatile Memory Express (NVMe) M.2 form factor SSD series. The SSDs have been fitted with Sandisk NAND (64-layer) and is powered the SanDisk 20-82-007011 series NVMe controller. This means WD can fabricate pretty much everything in-house. The SSD follows a smaller M.2 2280 (8cm) form factor so it will fit on most ATX motherboards capable of M.2 just fine. Have a peek, and then let’s head onwards into this review.
