Nonetheless, an excellent product from WD. Then again, if I were concerned about warranty/TBW or sequential throughput, the FireCuda 530 might get the nod. Random performance is what makes operating systems seem quick, and that is where the SN850X shines. If I was choosing a drive to anchor a new test bed, it would be the WD Black SN850X. SSD performance can vary by capacity due to more or fewer chips to shotgun reads/writes across and the amount of NAND available for secondary caching. The performance numbers shown apply only to the drive of the capacity tested. Over time, as a drive fills up, performance will decrease due to less NAND for caching, and other factors. Copy tests utilize an ImDisk RAM disk employing 58GB of the 64GB total memory.Įach test is performed on a newly formatted and TRIM’d drive so the results are optimal.

Internal drive tests currently utilize Windows 11, 64-bit running on an MSI MEG X570/AMD Ryzen 3700X combo with four 16GB Kingston 2666MHz DDR4 modules, a Zotac (Nvidia) GT 710 1GB PCIe x2 graphics card, and an Asmedia ASM3242 USB 3.2×2 card. What it didn’t show in CrystalDiskMark 8 in terms of sequential throughput, it demonstrated in the real world. The 1TB and 2TB (tested) versions are single-sided, and I’m guessing the 4TB is double-sided, hence the lack of a heatsink option.Īs you can see, the SN850X lacks nothing in performance. Indeed, while it’s less expensive than the FireCuda 530 at the moment, it’s still not cheap, with an MSRP of $160 for the 1TB model, $290 for the 2TB, and $700 for the 4TB capacity.Īdd $20 if you want a heatsink (most modern motherboards provide their own) for the 1TB/2TB capacities. WD Black SN850X: Price and designĪs you might guess given our glowing report on performance, you won’t be seeing the WD Black SN850X in the bargain bin. Go there for information on competing products and how we tested them. This review is part of our ongoing roundup of the best SSDs. It’s also a bit cheaper, though its TBW ratings are also far lower. It equaled or surpassed the mighty Seagate FireCuda 530 in a couple of tests, and by a rather wide margin in one.Įven if it couldn’t quite match its rival’s sequential throughput under synthetic benchmarks, the SN850’s overall performance makes it a more than viable alternative to Seagate’s best. WD’s Black SN850X lit up our test meters with outstanding real-world and random performance.
