  • Blazing Fast & PS5-Ready – Absolute Game Changer!
Capacity: 2TB Style: SSD w/ Heatsink
I couldn’t be happier with the WD_BLACK SN850X 2TB SSD! Right out of the box, this drive screams performance. Installation into my PlayStation 5 was a breeze, and thanks to the built-in heatsink, there were no worries about overheating or compatibility. The PS5 instantly recognized it, and I was able to move and play games directly from it without a single hiccup. Load times are virtually non-existent now—titles like God of War: Ragnarök and Spider-Man 2 boot up faster than ever. The Gen4 PCIe speed of up to 7,300 MB/s is no joke. Everything runs ultra-smooth, and the additional storage space means I don’t have to keep uninstalling games every time a new one drops. If you’re looking to upgrade your PS5 or gaming PC with a high-performance, reliable SSD, the SN850X is worth every penny. Western Digital nailed it with this one! ... show more

  • 4 Years, it's still a Plug-and-Play Perfection for PS5
Capacity: 1TB Style: SSD w/ Heatsink
As an average WD_BLACK user, I’ve come to expect reliable performance from their products, and this SN850 SSD lives up to the brand’s reputation. Installation & Setup: Super easy to install, literally plug-and-play. If you're using this with a PS5, the process is smooth and quick. Once installed, the console recognized it right away and formatted it without a hitch. No extra steps or tinkering needed. Performance Is Top-Notch: The SN850 runs like it is the PS5’s internal SSD. Game load times are identical, whether I’m playing directly off this drive or the built-in one. I’ve tested it with some larger titles and fast-paced games, and it handles everything effortlessly. Transferring games back and forth is quick, and performance remains stable even during longer sessions. The integrated heatsink does its job well, with no signs of overheating or thermal throttling. Built for Gaming: What I love about WD_BLACK is that their products are made with gamers in mind. This SSD isn’t just fast, it’s reliable, built well, and designed to meet modern gaming demands. I’ve used several of their drives over the years for both console and PC, and they’ve never let me down. This SSD is no exception. Final Thoughts: If you’re a PS5 owner looking for an easy storage upgrade that won’t compromise speed or performance, this is a perfect choice. It’s simple to install, works flawlessly with the system, and gives you the extra space you need to enjoy your full game library without constantly juggling files. WD_BLACK has once again delivered a product that hits all the marks—fast, dependable, and user-friendly. ... show more

  • Game-Changing Storage: SSD for PS5 Delivers Lightning-Fast Performance
Capacity: 2TB Style: SSD w/ Heatsink
The WD_BLACK 2TB SN850X NVMe Internal Gaming SSD with Heatsink has been an incredible upgrade for my PS5, and I couldn’t be happier with its performance. First off, installation was a breeze. I was able to follow the easy instructions and slot it into the PS5 without any issues. The heatsink was a great addition, and it fits perfectly without causing any extra bulk. Once installed, the console recognized it instantly, and I was ready to go. What really stands out about this SSD is how fast it performs. It’s as quick as the onboard storage, with load times that are virtually indistinguishable from the PS5’s built-in drive. Games load with no delay, and I haven’t experienced any lag or slowdowns, even when switching between titles or jumping into large, open-world games. I’ve noticed that it handles high-demand games with ease, loading everything seamlessly and offering smooth transitions during gameplay. Having 2TB of extra storage is a game-changer for me as well. I’ve been able to store all my favorite games without worrying about running out of space, and I don’t need to constantly uninstall and reinstall games just to make room for new ones. The performance is flawless, and the reliability of the WD_BLACK brand gives me confidence in its durability. Overall, this SSD is an excellent investment for any PS5 owner looking to enhance their gaming experience. It’s fast, reliable, and easy to install. If you’re looking for extra storage without compromising on speed, the WD_BLACK SN850X is a fantastic choice. Highly recommended! ... show more

  • Great quality drive.
Capacity: 4TB Style: SSD
Holds true to the top quality of the brand. I’ve used WD black drives for decades and this model is no exception to the speed and quality. I matched this with my NVMe heat sink I’ve had for years and still works just fine, install was simple as any drive can be. Bios recognized it right off the bat. Windows 11 partitioned and installed perfectly and crystal disc info shows all aspects working great. I upgraded from a 2Tb model that was still in perfect working order after almost four years of use. I think the days of SATA are nearly gone like EIDE or SCSI. ... show more

  • Nice Drive, Super Fast
Capacity: 1TB Style: SSD
Getting rated speeds in a Gen 3 slot. It's maxed out at the limit of Gen3. Gotta get a new CPU to get the actual rated Gen4 speeds in my mobo (dumb 10th gen Intel), but overall super happy. Dowloaded Macrium Reflect to clone my existing 500 GB Samsung SSD and it worked perfectly. Booted right up no issues. Plenty of drive space for what I'm doing, but get the biggest drive your wallet can afford you. At the time I bought this, it was the best deal out there for 1TB. I've been buying WD drivers for years and they have worked flawlessly. Not to discount other drives, but was happy to drop this new WD drive into my build. I didn't get the version with the heatsink just because my mobo already had a heatsink. Anyway, great drive, super fast, WD reliability. Can recommend. ... show more
