Lexar Professional NM700 M.2 2280 NVMe SSD 1TB Review
In the sea of storage, it is pretty easy to get lost. I always get questions from friends on what to get to replace their old spinning disk drives. The solution almost always lies with NVMe SSD drives. When picking the NVMe storage devices it always comes down to price vs performance. So our question to fiends is always: “Do you need the cheapest product or best-performing one?” For a general use NVMe I recommend one that has MLC or TLC flash as it is cheaper to the manufacturer and has higher capacities at affordable prices. Lexar is one of the manufacturers that produce NVMe SSD drives. Our review sample is a TLC flash-based SSD NM700 by Lexar. NM700 is an M.2 2280 PCIe Gen 3×4 NVMe 1.3 SSD that promises to deliver high performance for gamers, designers, or video editors.

Our sample came without any packaging. The retail version of NM700 will include a decorative box with all the specifications on it.
NM700 is 22 mm in width and 80 mm in length. There are no heat-sinks to keep this module cooled. There are two stickers on the module with some information such as the serial number and part number. Our sample is in 1TB capacity however Lexar also makes NM700 in 512 GB and 256 GB.
The PCB of NM700 has chips only on a single side. Here is the controller, cache, and RAM chips. The performance of NM700 varies based on the capacities. Advertised speed and IOPS vary. The 256 GB module has a sequential read speed of up to 3500 MB/s and sequential write up to 1200 MB/s (up to 200/240K IOPS). 512 GB module has a sequential read speed of up to 3500 MB/s and sequential write up to 2000 MB/s (up to 332/275K IOPS). 1 TB module has a sequential read up to 3500 MB/s and sequential up to 2000 MB/s (up to 293/272K IOPS).
