XPS L502X hard drive upgrade

Hi all,

New to the community/forum so if I am asking something that has already been addressed somewhere, my apologize but I didn't find an answer during my searching.

I have a XPS L502X that I want to install a SSD in.  I already know that I can do this.  However, what I want to know is what is the maximum capacity I can install.  I am hoping to up go to a 1TB drive but can't find any information whether or not I can do so. 

Maybe capacity isn't an issue, but I don't want to shell out the bucks if I can't use something that big.

Thanks in advance for the help.
