Upgrading my Hard Drives

[Volibear]

Okay so I currently have a 120GB Kingston SSD for OS and games, and a 2TB 7200rpm Seagate Barracuda for general storage (music, movies etc). I've noticed my SSD is almost full, so I was wondering what the better option was for upgrading. Should I:
A) Get a bigger SSD and move everything across?
Bi) Get a second SSD for more things?
Bii) Get a second identical SSD and set up a RAID0 config?
C) Get a PCI-e based SSD because they run faster?

If it were me (And I may be doing the same soon myself)... Get a bigger SSD, copy (clone) it over, sell the old one.

I'll be building a computer for my girlfriend soon, so that is the option I'm leaning towards. It'll save a bit of money on storage for her PC as well.

I kind of did the same thing you did. I got my 120GB SSD and then have a 1TB drive on the side. I recently got a 480GB SSD for not too bad. So I reinstalled my OS on the 120GB along with WoW and a few other programs, then I use my 480GB SSD for Steam and my other games/programs I want quick and then everything else on my actual hard drive.

As others mentioned, a bigger SSD is probably the best bet, assuming you couldn't simply move non-essential stuff off of the one you have to the 2 TB drive.

Bigger SSD and clone current 120GB drive on it. Can use the old SSD on a number of things including getting external USB3 case and turn it into really fast and lightweight external drive.
