Absolutely you can install an SSD up to and including a 4TB SATA SSD. This page at Crucial has examples though any quality SSD will work.
I have a Dell 3630 Precision Tower with a 250Gb PCIe SSD in one slot, and a 2TB HDD in a second slot.  I would like to upgrade the HDD to an SSD.  The spec sheet for this computer shows that the slot which currently has the SSD can accept a 2Tb SSD; however, the other SSD slot will only accept a 1Tb 2.5in SSD.  Can the 1Tb SSD slot accept a 2Tb 2.5in SSD, or will I have to use the slot which currently holds the 250G SSD?
