How about SSD of m2 interface? Why is it rarely used?

M.2 interface is a solid state drive, which is the fastest solid state drive at present. Few people use it because there are few motherboards that support this interface.

1, m.2 interface is the second generation msata interface, formerly called ngff, now called m.2. ..

2. The bandwidth of the 2.m.2 interface is 10Gb/s or 32Gb/s, far exceeding the 6Gb/s of sata3. It is the largest bandwidth hard disk transmission interface at present.

3.m.2 interface was originally supported from Intel's 9-series motherboard, so it is a relatively new interface, which supports fewer motherboards and is much more expensive than sata3 SSD, so it is not common.

Solid-state hard disk (SSD) is a hard disk composed of an array of solid-state electronic storage chips, which is composed of a control unit and a storage unit (FLASH chip and DRAM chip). Solid-state hard disk is exactly the same as ordinary hard disk in terms of interface, function and usage, and the product shape and size are also exactly the same as ordinary hard disk. Widely used in military, vehicle, industrial control, video monitoring, network monitoring, network terminals, electric power, medical care, aviation, navigation equipment and other fields.
