Lexar
Lexar NM620 1TB internal SSD with PCIe 3.0 NVMe interface and 1TB flash storage.
Up to 3,300MB/s sequential read and 3,000MB/s sequential write on this capacity.
M.2 2280 card installs in supported desktop or laptop NVMe-capable M.2 connectors.
3D NAND PCIe 3.0 NVMe, with an endurance rating of 500TBW for this capacity.
Suited to desktop application drives and gaming installations on compatible hardware without an external enclosure.
The Lexar NM620 1TB brings 1TB of internal storage to compatible computer systems. It is intended for system files, regular applications and a practical personal storage upgrade, using a M.2 2280 NVMe design and a PCIe 3.0 NVMe host interface. The NM620 uses NVMe over four PCIe 3.0 lanes.
The 1TB configuration is rated for sequential reads up to 3,300MB/s and writes up to 3,000MB/s. These are maximum sequential results rather than guaranteed speeds for every workload. The drive connects through a compatible PCIe 3.0 NVMe M.2 slot, avoiding the separate data and power cables needed by 2.5-inch SATA devices. Sequential transfer results describe continuous transfers rather than every application response.
The Lexar NM620 uses 3D NAND PCIe 3.0 NVMe. The manufacturer-rated endurance for this 1TB variant is 500TBW, representing a specified cumulative volume of writes. TBW measures cumulative writes, not speed. The available write throughput changes markedly between the lower and higher capacities. The M.2 2280 module requires an NVMe-compatible socket with an 80mm mounting position. Check the system's supported PCIe interface and any restrictions on shared lanes.
