4TB model compatible with PS5

Purchased 4TB SN850X NVMe for my PS5. Picked up a Sabrent HeatSink made for PS5. Fits like a glove. PS5 recognized the NVMe right away. I probably should have purchased the 2TB size, but decided to spend more to never worry about storage space issues. No issues with loading or saving games with over 50 hours spent on PS5 so far. Would definitely purchase again in the future.

Great for PC Gaming

This product worked exceptionally well, exactly as advertised. I installed it on my high-end desktop computer. Google claims it's one of the highest caliber options, and so far it lives up to that claim. I highly recommend it.
