I just installed an SSD in a mid-'11 21.5 and have a question about what to expect for performance. It boots up in a mind boggling 15 seconds, apps open instantly which is all amazing. However, opening pics is still not so snappy. I have a pic folder (262MB, 459 items) that while it populates instantly, it takes "forever" (15 secs) when I click on 1 pic for it to open. I'm using Preview, so all pics are loaded before I can open just 1. Shouldn't clicking on pic open it instantly?
