thanks, just checked my order, and accidentally it seems I ordered the one for the PCIe. I am almost sure my disk is SSD. should I be concerned?
Yes, you will short out the connectors. Order the correct version.

Thanks. I realized I might have misspoken.
I know for a fact the disk is M.2, what I don;t know if it is SATA or PCIE.
I am totally ignorant on this, it is a Samsung PM851.
I obviously get the difference between 2.5 and M.2, but is it that really different to have a M.2. SATA than M2. PCIE?
I ordered it seems the one for PCIE, is that the less risky or do I have to really match the type?

I think there's a misconception going on around here. The SATA and PCIe M.2 drives use the same tray. Part No. 4XB0K59917 and Part No. 4XB0L78233 have exactly the same specifications verbatim. If they were different, surely, they would differ in at least one measurement; but they do not.

thanks medwatt. I agree with you. specially after seeing the part first hand I realized, there is no way the same piece of plastic would not work for a PCIE or SATA. I think some people think teh tray woudl have connectors or anything electronic, while reality is that it is basically a piece of plastic with a screw hole.

Parts are not released just for the "fun of it". The connectors for the M.2 SATA and M.2 NVMe SSDs are different. Perhaps there is a notch on one of the trays to "force" the correct orientation of the card to the connection. Unless you've compared both trays side-by-side, I wouldn't jump to the conclusion that they are identical.

Lenovo salesperson confirmed to me the same part works for both. I did not order both to compare.
Out of curiosity, have you installed one tray? The open end is basically a whole with two plastic legs to rest on the upper part of the board; there is no connectors. Connectors are in the motherboard and obviously the m2 slots in the p50 accept pcie and sata so it should have a connector that encompasses both.

Actually they have exactly the same dimensions. The only difference, as far as I can say, is that one comes with an extra padding for the heat issues while the others does not. I got this from a Lenovo employee :
"Ok, straight from the North American Workstation Product Marketing Manager (long title...), the two trays are because we originally had planned for one tray for both PCIe and SATA, but upon installing both drives we found that damage was occurring to the SATA drives.
Come to find out, PCIe drives need more thermal padding and that extra padding was causing damage to the SATA drives when installing them in the same tray.
Hope this helps!"
