After doing quite a bit of overall searching, I thought I'd ask the masses about setting up a new MP for my workflow. JulianBoolean's thread has good information, but it's gotten pretty technical so I'm asking in terms I relate to. . . sorry Anyway. My main workflow is in 2D imaging. Photoshop, Corel Painter, etc. I may open Rhino for a 3D app, or play around in Maya at some later date to broaden my marketability I have been doing a fair amount of freelance, so reliability is a concern. Initially, I'd like to know about mirroring for file security. My current setup is a PowerMac G5 with a 74GB Raptor boot and 160GB Maxtor second storage drive (internal). I have an external LaCie for archiving. No issues with any of that hardware. Backup and archiving has been manual to this point. No Time Machine, etc. I just received a 3.2 quad MP. 6GB ram. I am looking to add an OCZ Vertex 2 60GB drive in the main boot drive for quick access. I bought two Western Digital 500GB Black caviars that I'd like to set up in a mirror configuration (is that sensible?) Possibly another SSD as a scratch disc for graphics and Photoshop work. My questions are : Is there a better drive than the Caviars for this use? Is an RE3 or RE4 any better for this application? Also, would any RAID make sense for me? I have never used RAID in any computers to date. Thanks for any advice.
