Lexar NM800 Pro (PCIe 4.0 NVMe/7,400 MB/s Read/6,500 MB/s Write/Performance Flagship) Review
The Lexar NM800 Pro is Lexar's performance flagship above the popular NM790, using a newer Silicon Motion controller pairing to push into the same 7,000-plus MB/s tier as far pricier big-name drives.
It's built specifically for buyers who liked the NM790's value proposition but wanted a genuine step up in peak performance and thermal handling, without moving all the way up to Samsung or WD flagship pricing.
Performance and Speed
7,400 MB/s read and 6,500 MB/s write place this drive alongside established PCIe 4.0 flagships like the Samsung 990 PRO and Seagate FireCuda 530, both covered elsewhere on this site, at a typically more competitive Lexar price point.
Thermal Design
The optional graphene heat spreader helps this drive sustain its rated speeds during longer write sessions, an important consideration at this performance tier since flagship-class controllers can throttle without adequate cooling under extended load.
Comparison to Sibling Products
Against Lexar's own NM790, also covered on this site, that drive remains the better value pick for buyers who don't need the absolute top speed tier, while this NM800 Pro is the choice for anyone wanting genuine flagship-class performance from the same brand. Against the Samsung 990 PRO, this drive matches its speed closely at a generally lower price.
Who This SSD Is Actually For
Buyers who want flagship-tier PCIe 4.0 speed without paying Samsung or WD pricing. This drive's numbers hold up directly against those established flagships.
Anyone who liked the value proposition of Lexar's NM790 but wants a genuine performance upgrade.
Not for the tightest budgets. Lexar's own NM790, covered elsewhere on this site, delivers most of the everyday performance for meaningfully less money.
