Cannot find any specs on what type, size, dimension, brand etc. hard drive I can get and fit into the empty WWAN slot on my W520-4270CTO laptop. Spoke to 5 people at Lenovo Tech support and they could not tell me anything. They had no idea. DOes a regular 500-1T/7200RPM drive fit, or do you need an SSD only for the space? (That's like 6X the $$$).

WWAN slot is a mini-PCI-e slot I would think... can you post specs?
The mini-PCI-e slot on there is mini-PCI-e only so a mSATA drive would not work, but that's an assumption-- would be very good to pull up the user manual or service manual and check. If you're thinking a 2.5" drive would fit then we could be talking about something else entirely...

Hi, found this photo of the supposed WWAN available slot under the keyboard.
Not sure what type/size drive fits in here.

That's probably mini-PCI-e only. You would need to check the manual to see if it's also a mSATA slot, however I would guess that is very unlikely.

Service manuals says mSATA SSD is supported, so any full size mSATA ssd should work(no regular drive for the slot). Make sure it is a W520 as most other notebooks won't have the electrical support for mSATA(aka will fit but not work). Looks like it shipped with a Intel 310 mSATA SSD which you can use a reference design on what to buy. Intel, Crucial, Samsung offer great selections, but won't be cheap as mentioned.
