Lexar has continued to expand their SSD lineup including the addition of their Lexar NM800 Pro which is available with and without a compact heatsink. The NM800 Pro sports an NNOGRIT 1G5236CAA controller which gives it PCIe Gen 4 capabilities and Lexar has it listed with read speeds up to 7450 MB/s and 6500 MB/s for its write speeds, at least on the 2TB model. This lines up well with other Gen 4 SSDs. Lexar is a long-respected brand and they gave their Pro-branded SSD a five-year warranty so I’m excited to put their new drive to the test and see how it performs. Today I will take a closer look to see what secrets it has to offer then we can run it through our test suite to see how it performs to find out if this is the drive to consider next time you are shopping for a new SSD.
