Review: The New Gold Standard for PCIe 4.0 Gaming - 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.

## Features

- Gain the ultimate gaming edge. Insane speeds up to 7,300MB/s (1TB - 4TB models) deliver top-tier performance with ridiculously short load times — for the elite gaming experience you’ve been waiting for.
- Heatsink for the win. All capacities have an optional heatsink version that's not only eye-catching, but also helps your rig maintain peak performance through your most intense gaming sessions.
- More room for more games. Capacities up to 8TB built with Western Digital TLC 3D NAND, means you get to keep more games at the ready — and get into the action even faster.
- Do more with WD_BLACK Dashboard. The downloadable WD_BLACK Dashboard (Windows only) monitors your drive’s health, lets you customize your RGB lighting, and, exclusively on the SN850X SSD, enables Game Mode 2.0 to transform your gaming experience.

### ⭐⭐⭐⭐⭐ Blazing Fast and Runs Cool — Perfect for Gaming
*by R***K on 10 May 2025*

I upgraded to the WD Black SN850X 1TB with Heatsink for my gaming pc after my ssd died, and it has exceeded every expectation. Installation was a breeze — it slotted perfectly into my motherboard's M.2 slot, and the built-in heatsink saved me the hassle of having to reuse the one i already had and made installing it easier The speed is incredible. Boot times are almost instant, and games load fast AF. I’ve also noticed smoother performance although thats probably due to having a fresh windows install. The heatsink does a fantastic job — even under heavy load, temps stay well within safe limits. It’s also PlayStation 5 compatible, so this would be a great option if you're looking to expand your PS5 storage with something fast and reliable. although i dont own one so cant comment on anything about that If you want top-tier performance with excellent thermal control, this drive is worth every penny. Highly recommended!
