Exceptional performance — perfect for AI and CUDA workloads!
I’m using the WD Black SN850X NVMe SSD for my local AI experiments and CUDA-based workloads, and it works like a charm. The read/write speeds are blazing fast — large model files load instantly, and data-intensive operations run smoothly without any lag. It stays cool even during prolonged GPU sessions and handles high I/O operations effortlessly. Installation was quick, and the drive has been completely stable since day one. A rock-solid SSD that delivers top-tier performance for developers, creators, and power users alike.

Review after 1yr and 3 months usage.
Excellent ssd, delivers what it promises. Been using it for windows and games. Boot time is almost instant, games load up fast af, transfer speeds are goated as well. Still at 100% health after 15 months. So yea I will 100% recommend going for this. 1 TB is definetly a life saver for me :)

Good WD 8TB SSD
Bought this SSD to use with new Mac mini M4 for moving the home folders to this. Tried with the 2TB SSD first which works well as does this. I am going to load it up to check how well it works. Doing this after my HDD failed after a side fall, a Seagate 16TB Expansion drive. Will post a follow up review about 6 months later to share the user experience. After initialising the drive it seems to work well and give me a speed higher than the native drive.

As expected.
Got it delivered in 2 days. Opened the PS5 back panel, open the SSD slot, inserted and closed it as instructed. Started ps5, formatted it when prompted to, and then changed the setting to enable all new games to save to the SSD. Works without any issues. 3 weeks into the usage.
