Sorry if this has been asked before, but I have tried to search in here and only found the confirmation for W520, and not for P50. I just got to ask prior of buying one, can I put and use mSATA SSD on P50 WWAN slot just like how it works on W520?
Solved! Go to Solution.

The WWAN slot, one can put wireless network cards, no use putting SSD/ M2 Sata.
Your IT department may be right. mSATA does not work in any given miniPCI slot. From wikipedia:
The connector is similar in appearance to a PCI Express Mini Card interface, and is electrically compatible; however, the data signals (TX±/RX± SATA, PETn0 PETp0 PERn0 PERp0 PCI Express) need a connection to the SATA host controller instead of the PCI Express host controller.
Put another way, slots that can support mSATA may or may not support miniPCI and vice versa.
The question you're really asking is if the WWAN (full miniPCIe slot) supports mSATA on your specific system, so the Lenovo link in your update isn't relevant - i.e. not all full miniPCIe slots support mSATA.

mSATA is an old standard and not compatible with any system made after 2012. You can´t use mSATA SSDs in the P50, mSATA is as obsolete as mPCIe, its parent standard.
You can use M.2 SSDs in the P50. But not in the WWAN M.2 slot. The P50 has two seperate 2280 M.2 slots, so you can have WWAN and an M.2 SSD at the same time. The P50 is a much more versatile system then the W520 in this aspect.
