M2 M Key Vs B Key

M 2 formerly known as the next generation form factor ngff is a specification for internally mounted computer expansion cards and associated connectors.

M2 m key vs b key.

Key 마다 각각 1 75핀 중 연결되는 핀이 있습니다. The m 2 specification identifies 12 key ids on the module card and socket interface but m 2 ssds typically use three common keys. B m or b m while a socket can only have one key. The pcie bus is faster than a sata bus and an m key ssd is faster than a b key ssd.

B m and b m. You will find the key type labeled on or near the edge connector or gold fingers. M 2 ssd의 b key 와 m key 정보입니다. 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. An m 2 ssd is keyed to prevent insertion of a card connector male to an incompatible socket female on the host. 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 replaces the msata standard which uses the pci express mini card physical card layout and connectors.

Uses both of the above gaps with five pins on the left side of the card and six on the right. M 2 ssd 의 종류인 b key 와 m key 슬롯입니다. 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.

Currently an m 2 ssd has either one of three key types. 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. Because of the physical design b m key cards are limited to pcie x2 speeds.

Ssd can only be installed one way. M 2 ssd s using the pcie bus are faster than m 2 ssd s using a sata bus.
