EE's: What IS this SSD Connector? see image

[cognus]

this is inside a Yoga 2 11. There is no info on this in the Yoga field service manual. I cannot so far find an image to match it by searching. it isn't normal msata; it isn't m.2; it isn't SATA [small]. I don't have a clue. it is for a solid state drive of some sort

well.... how does one attach an image in this forum?

 

[Saberus]

Can you upload a picture of it?

Upload it to an image hosting site like Imgur.

Looks like a mPCIe slots for wireless cards to me.

Over on the right, there is a small connector labeled SATA1, so I doubt it's mPCIe. It's M.2 B-keyed: https://en.wikipedia.org/wiki/M.2#Form_factors_and_keying

Thank YOU!!! I'm not seeing match to M.2 B: to me it looks like the depiction of "M Key" edge connector

the count on this is same as that one if I'm reading it right: 5-pin, 28-pin. I have not found a 5-pin anything so I didn't know what to call it. Any idea what the common trade name/designations might be?

Look at the connector closely at the short side: It's 6 pin on top, 5 on bottom. It matches the B connector perfectly. It's just called "M.2 B"

I stand thankfully corrected!
you are right - amazing how many times I have looked at that thing and missed the detail.
it does match up perfectly.
thanks for saving me wasted time & $$.
now the hard part is finding something that will actually work with the firmware. nowhere in the Yoga 2 11 manuals is any m.2 drive spec'd. there is a TBD entry... The drive that the tech guys at lenovo said was in the system originally was a M/B fulll monty type samsung. surely it is not feasible to 'hang' the unused tongue

 

[cognus]

am I reading this right? the following excerpt from the Wiki implies that the only single-notch production is "M" keyed. "B" is only employed in the full "2 notch" ??
paste:
.."For example, M.2 modules with two notches in B and M positions use up to two PCI Express lanes and provide broader compatibility at the same time, while the M.2 modules with only one notch in the M position use up to four PCI Express lanes; both examples also support SATA storage devices"

 

[Saberus]

Even with only two lanes on PCIe 2.0, that's 8Gbps of bandwidth, more than the SATA III interface it's connected to (6Gbps).

In a sense, 2 lanes makes it so a less complex signal processor/multiplexer can be used to provide full bandwidth. Supporting a full 4 lanes is overkill as there's already a bottleneck at 2.
