"Samsung has taken an interesting approach to PCIe Gen5 when it comes to storage. Their first Gen 5 offering was the 990 Evo, which did not really challenge the high-end Phison-based Gen5 drives already out, instead it was a more mainstream DRAMless drive. What was interesting about it, is that it only had 2 lanes of PCIe Gen 5, which is essentially the same as 4 lanes of PCIe Gen4. The new Samsung 990 Evo Plus is very much the same, still DRAMless and the same 2 Gen5 lanes. You are going to get better performance than the original 990 Evo, but on top of that better efficiency. According to Samsung the 990 Evo Plus has 73% higher power efficiency. This is made possible by their 8th generation 232-layer TLC NAND and firmware optimizations. This also mitigates a lot of the heat issues associated with faster M.2 solid state drives. We are taking a look at the 2TB model here today which has sequential read speeds of 7250 MB/s and sequential write speeds of 6300 MB/s."
