I have a 3.06 GHz 15in MBP with 4GB RAM and a 500GB 7200 RPM HDD. I am looking at getting a SSD to make the system quicker when working on larger files, opening up applications, and startup. I would then get a hard drive enclosure and use the 500GB as an external hard drive for backups and storage of media files. After doing some research it seems like the Intel X25M is one of/if not the best SSD out there. Is that still the case or is there another SSD you guys would recommend. I need a drive that is at least 160GB.
