This product is your standard PCIE 3.0 x4 NVME. It features QLC (quad level cell) NAND which enables it to have product variants up to 8TB due to its denser configuration! This type of NAND is of the 3D variant, which enables higher read and write endurance's, simply put they'll last longer. Compared to TLC NAND though, it is a bit slower in write speeds, still the drive promises up to 3000 MB/s in sequential write and 3400 MB/s in read, remember that max theoretical bandwidth for PCIE 3.0 x4 is 3940 MB/s, adding in all communications, transfers and etc., most we usually see on PCIE x4 is 3500 MB/s (that's like transferring COD Warzone from two same speed NVME's in about 15 seconds!!). On top of all this since the drive is in the typical 2280 format (22mm wide by 80mm long) and doesn't have a heatsink it'll fit in anything that has a slot the appropriate size. Now the cherry on the cake? Corsair offers a 5 year (!) warranty on this product line. Let's check it out this small, fast and capable NVME SSD!
