WD_BLACK SN850X 8TB, M.2 double-sided 2280 NVMe, Read speeds up to 7300 MB/s, Write speeds up to 6,600 MB/s, Gaming Expansion, PCIe Gen4 NVMe, High Performance Internal SSD, Black

The WD_BLACK SN850X in the 2TB capacity is a definitive update to an already legendary line, firmly positioning itself as a top-tier performer in the PCIe Gen 4 NVMe market. For any modern enthusiast or power user—especially gamers running large titles on a high-performance system like my Windows machine, Gengar—this drive provides a tangible upgrade in responsiveness, load times, and overall system snappiness. Blazing Speed and Consistent Performance The advertised sequential read speed of up to 7,300 MB/s is backed up by equally impressive sequential writes of up to 6,600 MB/s (for the 2TB model). These speeds are pushing the theoretical limits of the PCIe 4.0 interface. Gaming Load Times: The most noticeable benefit is the near-instantaneous loading of huge environments in modern games. The drive's strong random read/write IOPS performance (up to 1,200K/1,100K) means not only do sequential transfers fly, but the small-file operations that govern OS responsiveness and application launching are incredibly fast. Sustained Transfers: Unlike some budget drives that choke after transferring a large file, the SN850X maintains its blistering speed. This is crucial for content creators or engineers who frequently move massive media libraries or project files. Endurance and Longevity The 2TB model is rated for 1,200 TBW (Terabytes Written), backed by a 5-year limited warranty. This endurance rating is excellent for a consumer drive and offers significant peace of mind. Given that the average user rarely hits these thresholds, this drive is built to last far beyond the typical upgrade cycle. Form Factor and Management The standard M.2 2280 form factor makes installation straightforward in nearly any desktop or laptop supporting PCIe Gen 4. For those installing into systems with limited airflow, the non-heatsink version is sleek and easily fits under a motherboard's built-in M.2 thermal guard. Western Digital's WD_BLACK Dashboard software is worth downloading (for Windows users). It allows you to monitor drive health, thermal performance, and activate Game Mode 2.0. This feature is designed to optimize the drive’s operation when detecting game launches, ensuring maximum sustained speed by disabling low power states and prioritizing game-related I/O. The Verdict If you are currently running an older PCIe 3.0 NVMe drive or, worse, a SATA SSD, the WD_BLACK SN850X is arguably the best single upgrade you can make to your PC. It offers world-class performance for the PCIe 4.0 generation, excellent longevity, and the reliable engineering expected from the WD_BLACK line. For a primary boot/gaming drive that will eliminate loading screens and maintain rapid response times, this 2TB model is a stellar, professional choice.

Fast, reliable, easy to mount and heat pads take care of the heat. Ever tho my GPU fans are venting out right on to it, never had an issue in over 2y of usage. Software is also decent

Anyone looking to finally make a very late upgrade from HDD/SSD to NVMe please just do it, you will not regret it! The difference this one component makes to an entire PC build is so significant, just install the OS you are running on this drive and everything feels so much quicker and snappier. Dealling with older builds or even PC's at my work is almost a frustrating task now after being so used with the speeds you get with this. I have dealt with a few NVMe's now and all have been good but this one is fantastic because of the extra speeds of course but mainly just the value. Persoanlly I think it's great payong this price for such a great product and at 4TB, it's a component you can comfortably leave in your PC build for years and years.

Works great

The most important bit here is that it wasn't affected by "that" Windows 11 update that has been making a hash of other storage sticks in recent weeks. I installed Win 11 fresh, all the updates, all the office apps, some big games (all 50Gb+) without a problem. "Read speeds up to 7300 MB/s, Write speeds up to 6,600 MB/s"? Well, yes, actually. Pretty much on point to the claimed speeds which is surprising. Considering this isn't the latest gen PCI connector, but also considering I'm coming from "old" 2.5" SSDs and even a 4Tb platter SATA drive (5300rpm, lol), the speed at which this does its job feels insane, like we're living in the future. 4Tb on this tiny tiny stick. It's mad how far we've come. In the motherboard I have with a decent size heatsink on it, HW Info reported about 30-35 deg C even under load, so I stopped measuring it. Although I did make a new PC build with it (AMD 9800X3D, 5070Ti, MSI Mag Tomahawk X970E motherboard, Lexar Ares RGB 6000Mhz mem), bear in mind I have max 100Mpbs 5G connection for my rural internet. Previously downloading games of 50Gb plus would need me to leave the PC on overnight. With this build, Doom Dark Ages downloaded in about 90 mins. No exaggeration. I installed windows 11 fresh in about the same time, probably less. Office 365 was downloaded and installed in a ridiculously short amount of time. Maybe it's the CPU too, maybe it's the motherboard and Wifi 6 vs the old mobo having a 1Gb ethernet but I doubt that makes THAT much of a difference over a max 100Mpbs internet connection. Boot times are less than 10 seconds. I should time it, but it's almost like the PC is in sleep mode when booting from a "cold" power on. Loading "heavy" games (eg Doom Dark Ages, Indiana Jones Great Circle etc) is similarly insanely fast. Very happy with the purchase. More so as it was from Amazon Resale as "Good" (it's been perfect and about €20-40 cheaper than new new). I will probably end up getting a second one in time.

Delivered promptly. I was actually looking for a 2tb and had one in basket already when I came across this WD Nvme. I decided to go for this over 2tb to give myself peace of mind. The installation is as easy as it can be. WD provided cloning software which after downloading it took about 4 minutes to clone my older Nvme and that's it really! It's fast and reliable brand. Downloaded WD dashboard from their website to use T.R.I.M and it works flawlessly. Overall happy with the quality and price point of this product. Haven't benchmarked it yet but this is next on my to do list over the weekend. -TM
