Then, the second problem is compatibility.Ĭompatible system: Windows 10 and 8. M Key: For NVMe drives using the PCIe x4 bus.Īs the following picture shows, Samsung NVMe SSD 960 EVO has an “M-Key”. M+B Key: For SATA M.2 drives and some NVMe drives If you’re a laptop user, don’t insert the M.2 drive into the mSATA port.ī-Key: For SATA M.2 drives and older NVMe drives Because M.2 SATA drive and M.2 NVMe drive are using different keys. Insert NVMe SSD into your comptuerīefore you install your NVMe drive into your computer, the first thing you need to keep in mind is to check your motherboard.

In this part, you will know details about how to boot from PCle NVMe drive. If you set your NVMe drive as a boot drive, then your PC will get its best performance. NVMe design takes advantage of the low latency PCIe SSD and parallelism, which can greatly improve the user experience of SSD.

How to set NVMe as a boot drive for your Windows computer? M.2 NVMe: The PCI-E channel is different from M.2 SATA, the bandwidth can reach 10Gb/s. M.2 SATA: The theoretical bandwidth limitation of the SATA channel, the limit transfer speed can only reach 600MB/s. Data can be directly connected to the CPU through the bus, eliminating the need for the memory to call the hard disk, so the whole process is smoother and the speed is faster. However, things will be totally different if you choose M.2 NVMe drive. The data will be read from the hard disk to the memory first, then the data will be extracted to the CPU’s internal calculations, and then written into the memory, and finally stored in the hard disk. In terms of speed, the read and write speed of M.2 SATA is similar to that of 2.5-inch SSD, and the only difference is the interface.

However, the M.2 interface is divided into two types, supporting the SATA channel and NVME channel respectively. The M.2 interface is a new interface specification introduced by Intel to replace mSATA. The shorts of “Non-Volatile Memory Host Controller Interface Specification”, which is an interface protocol for PCIe bus. In this part, you can learn some crucial points about NVMe drive. What’s NVMe drive? Does it have any difference from other SSD? How to boot from NVMe drive? Can it save my slow computer?.
