Which types of SSD will be compatible with my XPS8700?

I have an XPS8700 desktop with 16GB RAM and Windows 8.1 bought in May 2015. My hard drive has become corrupted and it won't boot. My recovery plan is to buy an SSD, say 256GB, and fit it as the primary drive, and install Windows 8.1 on it, then run some data recovery software so that I can recover whatever is recoverable from my hard drive, then reformat the hard drive and use it as expanded storage for documents etc. Hopefully I then end up with a fully working system and better performance than I had before. My question is, what type of SSD will be compatible with this PC? It has a socket marked MSATA1 as well as several SATA sockets. I understand that his is not the same as M.2, and is not the same as PCIe.
