Usage: Video editing (Final Cut) and music (Ableton + Logic). I didn't think the RAM upgrade affected the speed enough. It still seems too slow when video editing. I'd therefore like an SSD. My MBP specs: Early 2011. 2.0 Ghz i7. 8 GB Kingston DDR3 (bought them afterwards.) 500 GB hard disk. Radeon HD 6490M (and that other gpu). So, I suppose this would have SATA 6Gb/s, but not sure if it has one or two SATA III ports? Capacity. Think I will remove my disc drive, and then use the two hard disks at the same time. I suppose a 256 GB would be nice, when video editing. Price. Definitely not more than 335 USD (don't know the prices compared to denmark, where I live, but not more than that please.) I actually found this extra cheap because it's second hand. What do you say? Hope you guys can/will help me. Thanks.
