INTRODUCTION

   With the very first consumer oriented PCIe 5.0 Gen 5 M.2 NVMe SSDs just around the corner (and the first motherboards to actually support them) it's no surprise to see that manufacturers are doing their best to further boost the performance of PCIe 4.0 Gen 4 models. Still with a top theoretical performance cap set at 8000MB/s and with most models not even being able to surpass 7000MB/s it's a safe bet that we're not going to witness a serious boost in transfer speeds before PCIe 5.0 models (just like we did from PCIe 3.0 Gen 3 to PCIe 4.0 Gen 4). It is what it is however and so today with me i have the latest and fastest PCIe 4.0 Gen 4 M.2 NVMe SSDs not only by Lexar but in general (always based on its advertised read & write speeds), the NM800 PRO.

   For more than 25 years, Lexar has been a trusted leading global brand of memory solutions. Our award-winning lineup includes memory cards, USB flash drives, card readers, solid-state drives and DRAM. With so many options, it’s easy to find the right Lexar solution to fit your needs. All Lexar product designs undergo extensive testing in the Lexar Quality Labs with more than 1,100 digital devices, to ensure performance, quality, compatibility, and reliability. Lexar products are available worldwide at major retail and e-tail stores. For more information or support, visit www.lexar.com.

   The NM800 PRO line of PCIe 4.0 Gen 4x4 M.2 NVMe v1.4 SSDs by Lexar is currently available in two versions (with and without the LPAH100 PS5 compatible heatsink - also sold extra) and in 3 capacities (512GB/1TB/2TB). The entire Lexar NM800 PRO line is based on the Rainier IG5236 eight-channel NVMe v1.4 NAND flash controller by Innogrit paired with 1GB DDR4L DRAM and 176-layer 3D TLC NAND flash. In terms of technologies the Innogrit Rainier IG5236 controller is fully packed with end-to-end data protection, LDPC (low-density parity check) error-correction with SRAM ECC, programmable RAID, smart cache, AES encryption and fully supports SHA, RSA, ONFI 4.1 and Toggle 4.0. Lexar also covers the entire NM800 PRO line with a 5-year limited warranty, reports a MTBF (mean time between failures) of 1.5 million hours and a DWPD (drive writes per day) of 0.535 (this translates roughly to a TBW of 500TB for the 512GB model, 1000TB for the 1TB model and 2000TB for the 2TB model).
