The Samsung 990 Pro with Heatsink is the fastest drive here on paper, with 7,450 MB/s reads and excellent power efficiency, and it has matured into an excellent all-around pick after early firmware issues were fixed. Tom's Hardware praises its low power draw and consistency. It runs hotter in the PS5 than the WD SN850X and costs a premium for similar real-world console results, which is why it lands second, but it is a superb, refined PS5 upgrade.
