In benchmarks, SSDs with PCIe-3.0 connector and AHCI get to speeds of about 1 GB/s, while SATA-connected SSDs with AHCI have data transfer rates up to a maximal 0.6 GB/s.

PCIe Generations and Lane Configuration

The true power of NVMe lies in its utilization of the PCIe bus2025年3月27日—PCIe Gen 3 M.2 SSDs deliverread speeds of about 3500 MB/s. PCIe Gen 4 M.2 SSDs deliver read speeds of about 7200 MB/s.. The M.2 slot can support different numbers of PCIe lanes (most commonly x2 or x4) and various PCIe generations (Gen 3, Gen 4, Gen 5), each offering distinct bandwidth.M.2

* PCIe Lane Configuration: More lanes generally mean higher potential speedM.2 vs PCIe vs SATA vs NVMe: What's the Difference? - Corsair. A common configuration for M.2 is an x4 slot. You'll get a maximum of about 3500 MB/s on an x4 slot due to the PCIe Gen 3 protocol. Conversely, an x2 slot will offer roughly half that speed. The concept of lanes also applies broadly; one lane equal to about 1 GB of transfer speed, and a 4-lane NVMe drive utilizes this to its advantage2025年11月25日—Our current top basic M.2 SSD for most users isCrucial's P3, for its balance of speed, capacity, and price; for performance upgrades, we suggest WD's Black SN ....
