The new Lexar Professional NM800 marks the manufacturer’s fastest SSD to date. The M.2 SSD relies on PCIe 4.0 x4 and comes with transfer rates of up to 7,400 MB/s read and 5,800 MB/s write in the top model with 1 TB capacity.
Finally with PCIe 4.0
In doing so, the Professional NM800 marks the manufacturer’s first SSD to rely on the PCIe 4.0 standard. The predecessor Professional NM700, which was released last year, only manages 3,500 MB/s thanks to PCIe 3 connectivity. Thanks to PCIe 4.0 x4, the new NM800 achieves double the data rate of 7,400 MB/s as well as 5,800 MB/s in sequential writing.
However, these values only apply to the model with 1 TB capacity. The NM800 with a size of 512 GB is a bit slower with a maximum of 7,000/3,000 MB/s during read/write. According to the manufacturer, the controller is manufactured in 12 nm, supports NVMe 1.4 and uses LDPC error correction. In addition, a 3D TLC NAND flash memory is used, but Lexar did not name a manufacturer.
In terms of Total Bytes Written (TBW), the Lexar Professional NM800 comes in at 250 TBW for the 512GB model and 500 TBW for the 1TB storage variant, which is not much, especially for SSDs for professional users.
Pricing and Availability
The Lexar Professional NM800 is still scheduled to go on sale in September 2021 and will be released in two different sizes. Starting off with 512 GB capacity for an MSRP of 109 euros. 1 terabyte of storage, on the other hand, costs 219 euros.
