The WD Black SN7100 succeeds the SN770 using the same 2280 form factor and features the same SanDisk proprietary Polaris 3 controller and 218-layer TLC (BiCS8) flash. The SN7100 drive is DRAM-less, which could concern some users, as sustained performance on this type of drive can degrade during heavy, prolonged transfers. The good news is that the drive supports HMB (Host Memory Buffer), which uses a small portion of your system RAM as the drive’s cache, so you won’t notice unless your workflow consists of frequent large file transfers to or from the device.
The drive delivers excellent random read performance and sips on power while doing so. In fact, the SN7100 sets a new low for PCIe 4.0 drives according to our review . Its efficiency makes it appealing for battery-powered devices like laptops, and it also reduces heat output. Our review showed the drive reaching up to 7,250MB/s in reads and 6,900MB/s in writes, and it has an above-average-for-the-capacity endurance rating of 1,400 TBW. Unless you’re really beating on this drive and transferring gigabytes daily, writes should never be a worry over its usable lifetime.
Save $200 and get a great deal on the 2TB WD Black SN7100 M.2 SSD. For only $299.99, you get a smokin'-fast PCIe 4.0 drive that sips on power and sure to be an upgrade in your PC, laptop, or PS5.
Priced at $299.99 and $200 off, the Western Digital Black SN7100 is a good deal. It not only offers a reasonable price for a PCIe 4.0-based drive, but it’s also one of the fastest DRAM-less available. Yes, you can have others for less. The least expensive 2TB PCIe 4.0 drive on Newegg is $249.99 , but it’s nearly half as fast. See our performance charts below for details on PC and PS5 performance.
