Corsair has been in the SSD game going all the way back to when it started and while the focus recently has been on PCIe Gen 4.0 drives for most companies. Corsair was early to that back when PCIe 4.0 was first available over a year ago at the X570 launch. With that in mind, they are still launching PCIe 3.0 drives as well to give new options for those who don’t have 4.0 or don’t want/need the extra speed or costs. So they introduced the MP400 this past October. It is available in 1TB, 2TB, 4TB, and 8TB options and features 3D QLC NAND. Today I’m going to check out the 1TB model which is Corsair's cheapest 1TB SSD option to test its performance and see how it fits in today's market.
