M2 M Key Vs B Key

The m 2 specification identifies 12 key ids on the module card and socket interface but m 2 ssds typically use three common keys.

M2 m key vs b key.

As the key positions of b and m are slightly different the m. The pcie bus is faster than a sata bus and an m key ssd is faster than a b key ssd. 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 cards with a b key interface can only fit into a b key host slot and likewise for m key.

Key 마다 각각 1 75핀 중 연결되는 핀이 있습니다. B m or b m while a socket can only have one key. An m 2 ssd is keyed to prevent insertion of a card connector male to an incompatible socket female on the host. A b keying pins 12 19 gives pci express ssds up to 2x lanes of bandwidth while a m keying pins 59 66 provides pci express ssds with.

Ssd using the sata bus run at sata speeds regardless of form factor. You will find the key type labeled on or near the edge connector or gold fingers.

The b and m module can plug into a b or m socket but a b or m module can only plug into a matching b or m socket. M 2 ssd s using the pcie bus are faster than m 2 ssd s using a sata bus. While a motherboard can incorporate a range of key m 2 socket options. 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 replaces the msata standard which uses the pci express mini card physical card layout and connectors. Ssd can only be installed one way. Because of the physical design b m key cards are limited to pcie x2 speeds. Uses both of the above gaps with five pins on the left side of the card and six on the right.

Employing a more flexible physical specification the m 2 allows different module widths and lengths and paired with the. B m and b m.
