Best Hard Drive Setup for Video Editing
I currently have a Macbook 6,1 and plan to upgrade the hard drive to tide me over until I can afford a Mac Pro. I'm going to remove the optical drive so that I can put a second hard drive in its place but could really do with some help on choosing a set-up. So, for video editing (FCP, Motion and Color) which of these options would be best (feel free to make other suggestions too):
1) RAID 0 two 500GB 7200 rpm mechanical hard drives together.
2) Use two separate 7200 rpm hard drives, one for the operating system and programs and the other for the file store.
3) Same as above but use a 120GB solid state drive for the OS and programs.
I don't know if the speed benefits of RAID 0 would be cancelled out by essentially having the OS on the same disk as the files. Ideally I'd like to have the OS and programs on a solid state drive and then RAID 0 two 500GB 7200 rpm drives together but I only have space for 2 drives!
Finally, I assume the bottleneck will always be the Macbook's lack of a dedicated graphics card. As such, is it even worth upgrading the hard drives (I do have 8GB of RAM installed)?
If you can help out a noob, I'd be really grateful!
