As seen in the bullets below, the original version of the PCIe Gen 3.0 NVMe M.2 SSD drive considerably improved read/write performance when compared to ordinary SATA III devices. The PCIe Gen 3 NVME read performance outperformed SATA III by 483 percent, while the upcoming PCIe Gen 4 NVMe devices (expected out in mid-2020) are 1,067 percent faster.
In high-level detail, the SPEC for each of the drive types available as of October 2020 is provided below:
- Traditional 7200 RPM HDD: 160 MB/s
- SATA III SSD: 600 MB/s
- PCIe Gen 3.0 NVMe M.2 SSD: 3500MB/s Sqq. reads – 3300MB/s Seq. writes – available mid-2018
- PCIe Gen 4.0 NVMe m.2 SSD: 7000MB/s Seq. reads – 5000MB/s Seq. writes – available mid-2020
