Can anyone recommend a high quality SSD drive for my 2009 Mac Pro 4 core? I currently have 16 gig's of ram and use the machine for Photoshop CS5, and Aperture 3. I just picked up a brand new Hasselblad H4D 40 (40 MP camera) and have noticed the larger files slowing the computer down. Also where does the SSD drive go? I have all four HD bays currently occupied with conventional HD's Thanks!
