M 2 Ssd Key Types

Ssd using the sata bus run at sata speeds regardless of form factor.
M 2 ssd key types. M is 4x pci and what you ll find on nvme drives. As the key positions of b and m are slightly different the m. The different key types are often labeled on or near the edge connector or gold fingers of the m 2 ssd and also on the m 2 socket. Ssd can only be installed one way.
The pcie bus is faster than a sata bus and an m key ssd is faster than a b key ssd. The m 2 specification identifies 12 key ids on the module card and socket interface but m 2 ssds typically use three common keys. Most m 2 wireless cards support both a and e key slots. Nvme sata m 2 download the infographic nvme non volatile memory express is a communications interface and driver that defines a command set and feature set for pcie based ssds with the goals of increased and efficient performance and interoperability on a broad range of enterprise and client systems.
An m 2 ssd is keyed to prevent insertion of a card connector male to an incompatible socket female on the host. Note that b keyed m 2 ssds have a different number of pins at the edge 6 vs. M 2 replaces the msata standard which uses the pci express mini card physical card layout and connectors. M 2 formerly known as the next generation form factor ngff is a specification for internally mounted computer expansion cards and associated connectors.
M 2 is a new form of connectivity that allows a ssd to connect directly to the pci e bus allowing for theoretical speeds as high as 2gb s. M 2 ssd pros and cons. All of these. This asymmetrical layout prevents users from reversing the m 2 ssds and attempting to plug a b keyed m 2 ssd.
M 2 ssd s using the pcie bus are faster than m 2 ssd s using a sata bus. However m 2 drives are complicated in that they allow for a variety of physical dimensions connectors and even multiple logical interfaces. Some motherboards are flexible offering mounting holes for the retention screw at some or all of these intervals. The common ones for ssds are b and m.

M 2 m key ssd s using the pcie bus are faster than m 2 b key ssd s using the pcie bus. Employing a more flexible physical specification the m 2 allows different module widths and lengths and paired with the. M keyed m 2 ssds 5.
