I currently own the following: http://www.everymac.com/systems/app...-2.4-aluminum-13-late-2008-unibody-specs.html It is however upgraded to 8GB of DDR3. My question to you is, how will I be limited? I am currently on Lion if it matters (Trim support?). Will I be limited to SATA 1.5 Gb/s | 3.0 Gb/s, etc? Things like that.
