Right now I have a SSD system drive and it's awesome. SSD is seriously where it's at! I have my scratch disk set to that same system drive for the time being. All my other drives as 7200rpm HDDs. I also have an external RAID 0 via eSATA where I store my media. I use FCP, After Effects, and Photoshop and I figure with my current configuration I get the best speed with my scratch being on the SSD even though that is my system drive. I know it is highly looked down upon to have a scratch disk on your system drive. And I assume equally as frowned upon living on your media drive. But is a SSD fast enough to handle both system and scratch? I can't afford a large enough SSD array to serves as a media drive to test having a scratch disk there. Would I find any gains having a separate small SSD for scratch alone?
