Is the SN850X fast enough for a PS5?

Yes. It meets Sony's requirements for a PS5 M.2 drive, and owners report fast load times. A heatsink version is the safer pick for the console.

Does it come with a heatsink?

The bare SN850X does not include one. WD also sells a heatsink version; pick that if your motherboard or PS5 needs cooling.

The SN850X is the newer drive, with higher rated speeds and Game Mode 2.0 for steadier writes. Real-world gains over the SN850 are modest.

For gaming, the difference is small today. PCIe 5.0 drives run hotter and cost more, so the SN850X remains a sensible choice.

The drive itself. Mounting screws and a heatsink are not included with the bare version.

For a large game library or big video files, it saves juggling multiple drives. Casual users get by with far less capacity.
