Lexar NM620 (PCIe 3.0 NVMe/3,300 MB/s Read/3,000 MB/s Write/Entry Gen 3 Value Pick) Review
The Lexar NM620 is Lexar's entry-level Gen 3 NVMe drive, sitting well below the NM790 and NM800 Pro we already cover and aimed at buyers who just want a cheap NVMe boot drive upgrade.
It's a fine, unremarkable budget drive, nothing wrong with it, but Lexar's own NM790 is close enough in price on many days that we'd only recommend the NM620 when it's clearly the cheaper option.
Performance and Speed
3,300 MB/s read and 3,000 MB/s write is a standard full-bandwidth PCIe 3.0 result, comfortably ahead of any SATA drive but well behind Lexar's own Gen 4 options. It's positioned purely as an entry-level upgrade path.
Positioning Within Lexar's Lineup
Lexar has built a reputation among enthusiasts largely on the strength of the NM790, covered elsewhere on this site, which punches well above its price on PCIe 4.0. The NM620 doesn't chase that reputation, it's simply the cheapest way into an NVMe drive from the brand.
Comparison to Alternatives
Against Lexar's own NM790, also covered on this site, that drive delivers roughly double the bandwidth on PCIe 4.0 for a price that's often surprisingly close, making it the better buy in most cases. Against the ADATA Legend 710, also covered on this site, a similarly positioned budget PCIe 3.0 option, the two trade blows on price and the NM620 rarely stands out either way.
Who This SSD Is Actually For
PCIe 3.0-only systems needing the cheapest reasonable NVMe upgrade.
Secondary storage drives where Gen 4 bandwidth would go to waste anyway.
Not for anyone who can find Lexar's own NM790, covered elsewhere on this site, at a similar price. It delivers roughly double the bandwidth for often marginal extra cost.

Expert rating6.3 / 10
A fine budget Gen 3 drive, but check Lexar's own NM790 pricing first since the gap is often small.
Best for
- PCIe 3.0-only systems needing the cheapest reasonable NVMe upgrade.
- Secondary storage drives where Gen 4 bandwidth would go to waste anyway.
- Buyers specifically shopping the lowest price point for an NVMe drive from an established brand.
Not for
- Not for anyone who can find Lexar's own NM790, covered elsewhere on this site, at a similar price. It delivers roughly double the bandwidth for often marginal extra cost.
- Not for PCIe 4.0 motherboards wanting to use the extra bandwidth.
- Not for buyers who want the longest possible warranty; the NM620's 3-year limited warranty is shorter than many rivals.
