Perhaps you guys can shed some light on some of my questions. I recently upgraded my old G75VW and have run into some issues.

I have a G752VY
Core i7 6700HQ
GTX 980m 4gb DDR5
48gb Ram
128gb SSD m2 and another open slot for another PCIE m2
1tb HDD 2.5 Sata

My question is, what is the largest capacity HDD you guys have upgraded to?
I find myself running low on storage constantly and having to clean up regularly and its getting to be a pain. I need somewhere along the lines of 3-4tb. Now they do make 2.5 Sata HDD that are 2,3, and 4 Tb, but theyre all like 15mm in height and I dont believe they will fit. So if anyone has upgraded for more storage can you tell me the size and possibly hook me up with a link on newegg or something that will indeed fit my G752? I'm not looking for externals... Just internals.

I appreciate the help. Thanks
