Frequently Asked Questions

Is the Lexar NM620 2TB NVMe compatible with my motherboard?

The Lexar NM620 2TB NVMe SSD uses a M.2 2280 form factor with PCIe Gen3 x4 NVMe interface. It is compatible with any motherboard that has a matching M.2 2280 slot. This includes AMD AM5/AM4 and Intel LGA 1851/LGA 1700 platforms. PCIe is backward-compatible, so older PCIe generation slots will work at reduced bandwidth.

Can I use the Lexar NM620 2TB NVMe in a laptop?

Yes, if your laptop has an M.2 2280 NVMe slot. Some laptops use shorter M.2 2230 or M.2 2242 form factors — the Lexar NM620 2TB NVMe SSD requires the standard 2280 (80mm) length slot.

What is the endurance rating of the Lexar NM620 2TB NVMe?

The Lexar NM620 2TB NVMe SSD is rated for 1,000 TBW with a 1,500,000 hours MTBF, backed by a 5-year limited warranty. At typical consumer usage of ~50 GB/day, this provides years of reliable operation.

How fast is the Lexar NM620 2TB NVMe?

The Lexar NM620 2TB NVMe SSD delivers Up to 3,500 MB/s sequential read and Up to 3,000 MB/s sequential write speeds. Random I/O performance: 400,000 read IOPS and 400,000 write IOPS.

What type of NAND does the Lexar NM620 2TB NVMe use?

The Lexar NM620 2TB NVMe SSD uses TLC flash memory with 2TB storage capacity. TLC NAND offers a good balance of performance, endurance, and cost.
