All of these.
M 2 ssd key types.
The m 2 specification identifies 12 key ids on the module card and socket interface but m 2 ssds typically use three common keys.
M 2 replaces the msata standard which uses the pci express mini card physical card layout and connectors.
This asymmetrical layout prevents users from reversing the m 2 ssds and attempting to plug a b keyed m 2 ssd.
B m or b m while a socket can only have one key.
B m and b m.
The pcie bus is faster than a sata bus and an m key ssd is faster than a b key ssd.
Ssd using the sata bus run at sata speeds regardless of form factor.
As the key positions of b and m are slightly different the m.
In a laptop for example an m 2 ssd takes up far less space and uses much less power than a standard sata or sas interface solid state drive.
Currently an m 2 ssd has either one of three key types.
M 2 m key ssd s using the pcie bus are faster than m 2 b key ssd s using the pcie bus.
M 2 ssd s using the pcie bus are faster than m 2 ssd s using a sata bus.
While the m 2 standard uses the same 22 millimeter wide slot for all cards it s not necessarily the exact same.
Size and capacity are two of the m 2 ssd form factor s greatest benefits.
An m 2 ssd is keyed to prevent insertion of a card connector male to an incompatible socket female on the host.
M 2 connectors have different keys.
Ssd can only be installed one way.
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 keyed m 2 ssds 5.
22 millimeters wide by 110 millimeters long.
M 2 formerly known as the next generation form factor ngff is a specification for internally mounted computer expansion cards and associated connectors.
Note that b keyed m 2 ssds have a different number of pins at the edge 6 vs.
The common ones for ssds are b and m.
Most m 2 wireless cards support both a and e key slots.
Some motherboards are flexible offering mounting holes for the retention screw at some or all of these intervals.
22 millimeters wide by 80 millimeters long.
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.
M is 4x pci and what you ll find on nvme drives.
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.
B is 2x pci and a lot of oem drives are b m keyed.
Employing a more flexible physical specification the m 2 allows different module widths and lengths and paired with the.
