Upgrading your PlayStation 5 storage is one of the best ways to expand your game library — and the WD Black SN850X is among the top SSDs officially recommended for the console. But one major question keeps coming up: should you buy the version with a heatsink or go without it?
While both versions share identical Gen 4 speeds and reliability, the difference lies in heat control and ease of installation. The PS5’s M.2 slot has limited airflow, which makes the heatsink’s role even more crucial. In this guide, we’ll compare WD Black SN850X With or Without Heatsink for PS5, exploring speed, thermal stability, setup convenience, and long-term performance.
