In addition, read and write IOPS is at 650,000 and 700,000. According to Crucial, the endurance of this M.2 NVMe SSD is 800TBW (terabytes written). Going by the math, you will have to fill up this drive completely, then delete it 200 times before it wears out, and that will take years, and by then, you would already have upgraded to the latest and greatest NVMe drive. Since it uses a standard layout, this Crucial SSD is compatible with any desktop or laptop computer with a vacant M.2 slot that supports PCIe Gen 3 drives. One thing that we should point out about 4TB M.2 NVMe SSDs; these models have memory chips on both sides, and if your laptop is not thick enough, it will not get installed properly. In that case, we do not recommend applying force because it can cause irreparable damage to the SSD. To find out if the drive will fit in your laptop, you will have to check out reviews of your particular laptop model. Other than that, this is a deal you should not miss out on.
