two scratch discs, set-up
Having just lost 2 years of media files for FCE projects (due to the failure of the single external HD I set as a scratch disc,) I now have two external HDs. (Three actually, but one is dedicated to Time Machine.)
I see that I can set them both as scratch discs in FCE, but the guy in the store said it might be better to have one set up as the FCE scratch disc, and the second one mirrored using RAID. Does anyone have any advice on which is the preferable method please?
How does FCE access the data if it is stored on two separate drives, or don't I need to be concerned about that? I just want to be sure that I don't lose my projects again. Thank you. Keith
