My video hobbie has gotten pretty serious and I thought I had all my problems solved with a Mac pro. Seems not as now hard drives seem to be reproducing in my house. I.E- HDV footage w/ color correction is alot of GB. SO I know about RAID 0/1/5 but not 10. My questions are: 1. do I want to have a RAID 5 external for my scratch disc & capture drive? I would assume 5 drives. 2. Or have 2 external RAID 0. One as a capture and one as scratch disc. This way I could have my 4 drives in my comp as OS, Win7, Storagex2 any other mixes and flavors?
