SSD M.2 for the HP Probook 650 G1

[vladnl]

I want to install SSD M.2. But I'm not sure, since there are 2 kinds of contacts. The one that I think is 80 mm long Samsung 960 Series (OEM) 256GB NVMe M.2 NGFF Pro SSD PCIe 3.0 x4 80mm - (PM961), the one that is 42 mm. 256GB NGFF M2 2242 SATA 

, Which fits in length, has a different contact than the slot into which it should be inserted.
Tell the experts which model of ssd m.2 I can use for the HP Probook 650 G1

The 42mm you linked will work fine. M.2 disks come in a variety of types of "keys". You have "M" which is a 2 prong and is used on pcie/nvme disks. Your laptop willnot work with those. Then you have B + M which is a 3 prong connector and most commonly used on SATA M.2 disks. The thing that confuses many people is that all M.2s will fit in the same 2-chamber socket. The 3 prongs on a SATA M.2 disk will fit right into the 2 chambers in the M.2 port. See these pictures. Your M.2 SATA is obviously shorter in length (42 vs 80 mm) but this shows the connector type.

Post back with any more questions but please accept as solution if this is the answer you needed.

Thanks for the explanation! I correctly understood that both can be used for a slot in my laptop?

 

What is the difference in these modules, why are the contacts different?

No yours supports the SATA M.2 disks only.
