Under the Lexar brand, sold to the Chinese company Longsys in 2017, the NM620 M.2 2280 NVMe PCIe solid-state drive, equipped with a PCle Gen3 x4 interface and supporting the NVMe 1.4 protocol, is presented. It uses TLC 3D NAND flash memory.
The PCIe NVMe drive is available in 256 GB, 512 GB and 1 TB sizes. The sequential read speeds reach 3000, 3300 and 3300 MB/s, respectively, and the sequential write speeds are 1300, 2400 and 3000 MB/s, respectively. As for performance on operations with random access, in read mode it reaches 92,000, 200,000 and 300,000 IOPS, respectively, and in write mode – 240,000, 256,000 and 256,000 IOPS, respectively.
The resource of the 256 GB NVMe PCIe drive is declared equal to 125 TBW, 512 GB – 250 TBW, and 1 TB – 500 TBW. Unlike traditional hard disk drives, the NM620 SSD has no moving parts, so it’s built to last. It’s also shock and vibration resistant, making it a robust and reliable SSD. These values are equivalent to 0.44 full rewrites per day during the five-year warranty period.
