For just $516.89, down from its list price of $759.99, this 4TB drive lands well below the 30-day average of $674.59 and the 90-day average of $682.84. It's one of the deeper discounts on a high-capacity Gen4 SSD this year, especially from a brand that consistently delivers strong sequential performance.

What You're Getting

The Lexar NM790 is a PCIe Gen4 x4 NVMe M.2 drive rated at 7400MB/s read and 6500MB/s write, with a 3000TBW endurance rating that puts it in the same league as drives costing more. It uses Host Memory Buffer 3.0 to use your system's DRAM instead of carrying its own cache, which cuts power consumption by up to 40% compared to DRAM-equipped Gen4 drives. The integrated heatsink keeps thermals under control during sustained writes, and it's fully compatible with the PlayStation 5.

Who This Is For

Best for: PS5 owners who need a 4TB expansion drive without the Sony tax, and PC builders who want Gen4 speeds without paying a premium. If you're on a Gen3 platform or don't need 4TB of storage, smaller-capacity versions of this drive cost less. But for anyone maxing out a build or console, the per-terabyte cost here is hard to beat.

Final Verdict

At $516.89, this undercuts most 4TB Gen4 SSDs by a meaningful margin while delivering the same peak speeds as the Samsung 990 Pro and WD SN850X. If you need the capacity now. This is the price to jump on.
