Nowadays everyone want to be slin and beautiful, and our computers are getting smaller and smaller too. Laptops, netbooks, and ultrabooks are smaller and smaller than othereach. In response to the times, Intel make m.2 interface specification for Ultrabook to replace MSATA. Compare to mSATA, m.2's faster speed and updated specifications allowed it's quickly occupying the mainstream market.
At present, the HYSTOU mini pcs which has m.2 slot for solid-state hard disk mainly is kaby lake R series, such as P03B-i5-8250U, P05B-i7-8550U, M10-i5-8250U and M10-i7-8550U.
There are two types of slot ends (motherboard ends) of the m.2 interface, one is B Key (also known as Socket2) and the other is M Key (Socket3), and the M Key is used on the Hystou mini pc's motherboard (picture as above); However, the m.2 interface (solid state hard disk pin header design side) has three designs as shown below, in which the third B&M key is compatible with the first two, it means, the third type SSD can be used on both design on the motherboard.
