So, about 6 months ago I bought the 27" i7 imac.. 16GB RAM, and the 1TB HD. I got it for my photography / video business. I also use a second 27" LED Apple display too. I have a ton of external drives connected.. I have three g-safes and one g-tec drive for time machine. They all have to be daisy chained together. The g-safe drives store photo files, and video in RAID 1, and I work from them often. So, the issue is that the system is slow as hell.. and I want to throw it out the window. I feel like I either need to buy an SSD, or sell it and buy a Pro. I use Aperture 3, CS4 and Final cut all the time. Thoughts?
