I make motion graphics for a living using After Effects, Cinema 4D, PS and AI. I recently bought a 2.66 8-core Nehalem and have another 16GB of RAM on the way to give it 24GB total. Next step is to sort out the storage. Most of my jobs require 5 - 10 GB of data (including renders) with the odd job needing more like 50GB (if I shoot a lot of HD video). I rarely work on anything longer than a couple of minutes and they tend to be heavier on vector + bitmap assets than video files. Once a job is finished it all gets archived to 2 separate external FW drives. I don't tend to backup during jobs which is something I should probably change. I have another external HD for Time Machine which backs up my OS and most importantly, emails. My plan was to put a 100GB SSD in to run the OS, applications and probably my home folder; then striping two regular drives (WD RE's most likely) with software RAID 0 for all my working and render files. But then I started wondering if I would see a better performance from using an SSD for my working files too. I've spent too much already this year so am trying to get some sort of performance on a budget, eg. about another £300 - £400... If I use an SSD only for the OS, Apps + Home do I really need to worry about getting a drive with greater over-provisioning such as the OCZ Vertex II, when I can buy the Extended Edition or the 3.5" Version quite a bit cheaper? When using After FX should I be reading my assets from one drive and rendering to another to increase performance?
