How to tell empty m.2 ssd slot type?

Hello. I have a Thinkpad Edge E531 and want to get an m.2 SSD for it, but I read that this model can have either type (SATA or PCIe). is there a way to tell which type mine needs with the slot empty? I will post what I think might contain something relevant, but if there's another way, please share. I just don't know what to look for. Any help would be greatly appreciated. I've been reading for days and still I'm not sure. I even checked the crucial.com site and it only listed 2.5" SATA SSDs.

ThinkPad Edge E531 SSD Upgrade : Lenovo (reddit.com)

According to the poster they are using this:

Amazon.com: Transcend 128GB SATA III 6Gb/s MTS400 42 mm M.2 SSD Solid State Drive (TS128GMTS400) : Electronics

Not cheap by any means though.

All I did for mine was to visit the Lenovo site and add the model number.

Thank you very much! I read one very similar to that Reddit thread, I think it was in the Lenovo Forum, and someone who seemed to know a lot about it said that some were using NVMe and some were using SATA, whatever slot they had. When I first started reading the Reddit link, for a second I thought it was that same thread I already read. I bet that's how I overlooked that Reddit one. Thanks to you both and I will check that link as well, @sammiev .

I like the way the page for yours has a Storage Support section....mine doesn't. For mine it only tells what kind of hard drive it came with. Lol.

Wish I could have been more help.

Wow!! $160 for 256GB!! You're sure right!! Blah!! But ebay has much better deals. Look at this one, and there are better deals than this too.
