I'm running out of space on my C: Drive. Currently a 60gb SSD. Is it possible to add another hard drive and merge the drives (add space to current C drive)?
Short answer is no.
You can't add space to a drive that has a finite space limit, in your case 60GB. You can physically add another drive but that won't expand or merge the space of your SSD. The best solution is to add another Hard Drive and transfer all extra or unneeded files over to the second drive and if that does not give you enough space then uninstalling any large apps from C: and then reinstalling to your new Hard drive will relieve some space as well as changing the location of your swap file from C: to the other drive.
