[SOLVED] M.2 Storage Interface types question

[Clonimus74]

Hi all,

I want to buy a Gigabyte motherboard, I'm considering one of the following:
Z490 AORUS MASTER
Z490 AORUS ULTRA G2
Z490 AORUS ELITE AC

I plan on using SSD drive connected via M.2 slot, the thing is that in the spec they specify different types of M.2 interfaces, can anyone tell me the difference between:
M2P_SB, M2A_CPU, M2M_SB and M2A_SB

Thanks

1. 1 x M.2 connector (Socket 3, M key, type 2242/2260/2280/22110 PCIe x4/x2 SSD support) (M2P_SB)
2. 1 x M.2 connector (Socket 3, M key, type 2242/2260/2280/22110 SATA and PCIe x4/x2 SSD support) (M2A_CPU)
3. 1 x M.2 connector (Socket 3, M key, type 2242/2260/2280/22110 SATA and PCIe x4/x2 SSD support) (M2M_SB)

Seems M2A_CPU and M2M_SB are SATA and PCIE, but what's the difference, what does the M2P_SB, M2A_CPU, M2M_SB and M2A_SB mean?

M2A_CPU just the id to the slot so you can see where it is in the manual.

Different labels for different M.2 ports.

Each motherboard has different properties and capabilities.
