Lexar NM620 512GB NVMe Drive

The Lexar NM620 is a 512GB internal SSD built for consumer desktops and laptops. It uses a PCIe Gen3x4 NVMe interface to deliver sequential reads up to 3300 MBps and writes up to 2400 MBps. Random performance reaches 200,000 read IOPS and 256,000 write IOPS. The drive targets PC enthusiasts and gamers who want faster load times than a SATA-based SSD.

M.2 2280 Build and Connectors

The single-sided M.2 2280 module measures 80.00mm long, 22.00mm wide and 2.25mm high, weighing 9.00g. It draws up to 3497 mW during reads and 3196 mW during writes. With no moving parts it survives 1500G shock and vibration from 10 to 2000 Hz at 20G. Operating temperatures span 0°C to 70°C and storage temperatures span -40°C to 85°C.

Upgrading from SATA or Older NVMe

The NM620 provides roughly six times the sequential throughput of a typical SATA SSD. A 250TB write endurance rating and 1,500,000-hour MTBF support heavy daily workloads. LDPC error correction protects data integrity on the 3D TLC NAND. The jump is worth it when boot drives or game libraries still sit on SATA or on an earlier Gen3 drive with lower IOPS.

Questions about this item

What practical throughput does the PCIe Gen3x4 NVMe 1.4 interface cap at for this NM620?

The interface supports up to 3300 MB/s sequential read and 2400 MB/s sequential write, with 200000 IOPS random read and 256000 IOPS random write.

What physical slot and dimensions does the M.2 2280 form factor require?

It fits a standard M.2 2280 slot measuring 80.00 mm long, 22.00 mm wide and 2.25 mm high, weighing 9.00 g.

How is the drive installed, and which step is often missed?

Insert the drive at an angle into the M.2 slot, press flat, and secure with the motherboard screw; many forget the screw and leave the drive unsecured.
