M910 SFF & Tower: M.2 slots and M.2 storage questions

2017-07-03, 1:14 AM

I don't know if the two M.2 slots on the M910 motherboard (for both SFF and tower cases) are really identical and can actually support two real M.2 storage drives. The specs talk about only one M.2 storage drive.

 

 

The diagram show two M.2 connectors, but one is described as "M.2 storage drive slot" and the other is "M.2 WiFi card slot".

 

 

The M.2 SSD Kit (Part #4XF0P01011) which is needed if you actually want to install one/two M.2 cards in these machines (since the required mounting bracket is not provided with the case, but must be ordered separately as part of this M.2 SSD Kit for $9.99) has the two bottom pieces to which the one/two M.2 cards you use would be tightened down.  So physically, it seems you could clearly have one or two M.2 cards.

 

But as to whether or not the so-called M.2 WiFi card slot can just be used for holding a second M.2 storage drive, well I don't know.  I don't know if there's anything which would prevent this, if both connectors are on the PCIe bus and have the same bandwidth.

 

Anybody know for sure, one way or the other?

 

Mod:  moved question to to own thread, since SFF & Tower use different motherboard than Tiny

Slots designed for WiFi are keyed (notched) differently than storage.   WiFi uses an A and E key, storage uses B and M, and cards are sometimes keyed for both B and M.   Because of the keys, cards cannot be put into the wrong slot.

Thanks for clarifying.

 

I've quoted your reply on this other thread contrasting M710 vs. M910, as your answer seems to be relevant there as well.
