Keying and Compatibility

M.2 slots and cards are designed with different keying configurations, which prevent incorrect insertions. Keying is indicated by a notch on the connector edge of both the slot and card. The most common keying types are:

• M Key (B Key): Supports SATA (2.5Gbps) and PCIe (up to 4x)
• B Key (M Key): Supports SATA (2.5Gbps) and PCIe (up to 2x)
• M Key Only: Supports PCIe (up to 4x)
• B Key Only: Supports SATA (2.5Gbps)
• E Key: Supports USB 3.0

M.2 SSDs: Form Factors and Performance

M.2 SSDs come in various form factors to accommodate different M.2 slots. The most common form factors are:

• SATA (2.5Gbps): M.2 2242, M.2 2260, M.2 2280
• PCIe NVMe (up to 4x): M.2 2242, M.2 2260, M.2 2280
• PCIe NVMe (up to 8x): M.2 2280, M.2 22110

PCIe NVMe (Non-Volatile Memory Express) SSDs offer significantly higher performance compared to SATA SSDs. They can achieve sequential read/write speeds of up to 3,500/3,000 MBps, respectively.
