I'm planning on getting the SSD + 2TB drive option for my new iMac and using the 2TB drive as a scratch disk for final cut (as well as my itunes media drive and a few other things). My question is will this much use on the drive be bad for it? Right now I'm just using external drives and when they fill up I get a new one so I don't put as much use on them as I would with the 2TB drive where I plan on just archiving the footage onto a external hard drive when I am done with project and then continue using the 2TB drive for my next project.
