The Corsair MP600 Core XT is a mid-range, QLC-based PCIe 4.0 NVMe SSD designed to offer additional capacity at a reasonable price. It’s very similar to the Crucial P3 Plus with all the same advantages and caveats, although it is currently slated to be more expensive. However, this price will likely decrease after launch and provide a reasonable alternative for additional, fast storage.
QLC flash lacks TLC's endurance and performance characteristics, but often this can be difficult to tell, particularly when paired with a solid controller like the Phison E21T. The MP600 Core XT offers nothing new or exciting here, but more competition is a good thing. In addition, recent SSD pricing trends are making large SSDs more affordable, and this drive is sufficiently faster than older PCIe 3.0 options to make it a comfortable selection.
