"We first saw PCI-Express 4.0 NVMe solid state drives back in 2019 when AMD launched their X570 motherboards. Samsung seemed to be a little late to the Gen4 party as we've seen plenty of Gen4 drives launched over the past year and a half. Today we are checking out Samsung's new 980 Pro PCIe 4.0 NVMe Solid State Drive. This drive features sequential read and write speeds of 6900 MB/s and 5000 MB/s respectively. Another interesting thing is that before this drive Samsung did not have a "Pro" drive for almost 2 years. Typical "Pro" series drives from Samsung always featured 2-bit MLC flash, but the new 980 Pro makes use of 3-bit TLC flash. While MLC has better endurance and typically better performance, TLC is far less expensive. Let's get this drive installed and see what it is all about!"
