Lexar NM700 256Gb NVMe review

Lexar NM700 256Gb use Marvell 88SS1092. The NM700 comes equipped with 3D TLC memory. This drive is offered also in 512 Gb and 1 Tb capacities.

Performance and benchmarks

NVMe SSD works on PCIe M.2 3.0 x 4 computer expansion bus standard with sequential write speeds equals to 2000 Mbps, and maximum read speeds 3500 Mbps. This model has IOPS 272000 on writing and 293000 on reading operations per second.

Endurance and warranty

As well it has 1.5 million hours mean time between failure.

NM700 (256Gb) produced by Lexar may work on previous bus standard that is significantly slower than PCIe Gen4. The write speed is 2000 Mbps, that is common for this computer expansion bus standard. The NVMe SSD has endurance 150 TBW, that is not very much compared to rivals. After evaluating all the facts, Lexar NM700 256Gb has more cons and we highly do not recommend to purchase it.

+ Pros

  • Good writing speed

- Cons

Lexar NM700 Gen 3x4 NVMe M.2 - Is It The One to Get?


The Lexar NM700 has no dynamic random-access memory (DRAM) in their controller or data about it is unknown. Dynamic random-access memory (DRAM) in their controller help to improve endurance and IOPS.

The Lexar NM700 256Gb due to the low density of memory chips can run with no further heat sinks. Some motherboards already has thermal pads below and above the storage for better productivity during high loads.

The NM700 256Gb has maximum write speed 2000 Mb/s, sequential read speed 3500 Mb per second. NVMe works on Marvell 88SS1092 controller and M.2 3.0 x 4 interface standard. The NAND flash memory type is 3D TLC.
