Lexar recently expanded on their gaming lineup and one of the new products that they have added into the mix is their new NM790 SSD. It is a PCIe 4 SSD with the standard 2280 M.2 form factor using four lanes. This isn’t Lexar’s first PCIe 4x4 SSD, in fact, they have 7 other models that fall into that category. But even though PCIe 5.0 drives are now also on the market the PCIE 4 drives are still the sweet spot. The NM790 is a DRAMless design that they are looking to put behind the NM800 Pro which has DRAM in their lineup. Today I’m going to see what it is all about then put it to the test, then when I’m done we can see how the NM790 is positioned in the market to find out if it’s a good option for your next build.
