Ok so I just installed a samsung 840 250gb ssd in my main bay in my early 2011 15-inch MacBook Pro. I ordered a owc opitical drive replacement bay for my stock 750gb hdd. But now I'm thinking about a second samsung ssd instead. I would run this as a raid 0. I'm thinking instead of a 1tb fusion with a slow 5400rpm hdd and ssd. It would be beast mode with 2 ssd in raid 0. Has anyone tried this set up with any luck. Would trim be a issue or can trim enabler handle a raid 0? Any thoughts suggestions? I run all my stuff externally then move files I need to main hdd as I'm working. Hd video editing on final cut. Then when done store externally so 500gb would be more than enough. Also figure would be same as fusion if one hdd goes out there both dead. So if I'm correct this would be more reliable no moving parts with ssd.
