Lexar NM790 with Heatsink

4.1

3 sources$188.49as of Oct 11

The Lexar NM790 with Heatsink is the value pick. It is often the cheapest high-end Gen4 drive, reads up to 7,400 MB/s (enough to fully saturate the PS5), and ships with a heatsink so it drops straight into a console. Tom's Hardware was pleasantly surprised that it rivals high-end PCIe 4.0 drives, and TechRadar calls it the best value PS5 SSD. The DRAM-less design trails DRAM drives under heavy sustained load. For the lowest price that still gives you full PS5 speed, this is the one.

Strengths

— Up to 7,400 MB/s reads, fully saturating the PS5's interface
— Bundled chunky heatsink adds PS5 compatibility out of the box
— Tom's Hardware found it rivals high-end PCIe 4.0 drives

Watch-outs

— DRAM-less (HMB) design trails DRAM drives under heavy sustained load

Ranked #4 in Best SSDs for PS5 Upgrade

WD_BLACK SN850X with Heatsink

3.6

2 sources$267as of Oct 8

The WD_BLACK SN850X with Heatsink is the best all-around PS5 SSD. Tom's Hardware ranks it at the top of its PS5 list with an Editor's Choice award, citing 7,300 MB/s reads that clear Sony's requirement and a heatsink that drops into the expansion slot with room to spare.

Strengths

— 7,300 MB/s reads exceed Sony's PS5 requirement with margin
— Bundled heatsink fits the PS5 expansion slot with room to spare
— Excellent all-around value with frequent discounts on the 2TB model

Watch-outs

How they stack up

Lexar NM790 with Heatsink

The Lexar NM790 is the budget value leader, undercutting the WD SN850X, Samsung 990 Pro, Crucial T500, and Seagate FireCuda 530R while still hitting the read speeds the PS5 needs. Its DRAM-less design is the trade-off versus the DRAM-backed Crucial T500 and the premium WD and Samsung drives, but it saturates the console's interface for less money than any of them.

WD_BLACK SN850X with Heatsink

The SN850X is the all-around PS5 pick, running cooler than the hotter-running Samsung 990 Pro while nearly matching it on speed. It is pricier than the budget Lexar NM790 and the value-oriented Crucial T500, and competes closely with the Seagate FireCuda 530R, but its combination of thermals, speed, and PS5-fit heatsink puts it first.
