I often read comments from people recommending that you should keep all your clips on a scratch disk and edit from there as opposed to keeping things on your internal hard drive. What are the reasons/advantages for doing that?
I keep a fair amount of GBs of files on my main MAC hard drive. Not just related to editing, but all sorts of stuff - tutorials, films, different apps, etc. Is this a bad thing for my editing performance?
Shane's Stock Answer #43 - Types of hard drives and how they compare when working with video
Drive types and how good they are when it comes to dealing with video...
USB 2 = BAD
Firewire = GOOD
e-SATA = more GOOD
Internal SATA = more better GOOD
eSATA RAID = more MORE better GOOD
4 gig FIbre = Just about the best you can get! (great for SAN networks)
External PCIe = Da Bomb! 5 times faster than Fibre
