Hi all, I am currently upgrading my work station. I have been researching cost-effective ways to expand my current setup. The main thing I want to do is to split the workflow up correctly. Namely, have a separate external hard drive for each stage of the workflow: 1) capturing and storing video files; 2) generating previews and media cahches; 3) exporting final video. I want a separate external hard drive for each job, as this seems to be the standard most effective way to run an efficient workflow without bottlenecks. The trouble I am having is choosing which external hard drives to use. In particular, which connection to go with. I am tempted to daisy-chain 3 firewire hard drives. BUT I am using a 21.5 inch late 2009 iMac (soon to have 16GB RAM - currently only using 8GB). Graphics ATI Radeon HD 4670 256 MB, 3.06 GHz Intel Core 2 Duo. . I have heard some folks say that daisy-chaining firewire hard drives from a single firewire port (which my iMac has) is bad, and causes bottlenecks (whilst others say it;s fine). My iMac port is firewire 800. Other options are gigabit ethernet hard drives? Should I get solid state hard drives? Do they come with firewire connection? Should I get 1 SS and 1 normal hard drive? Or should I get 1 external firewire hard drive and just partition it to save daisy-chaining from a single port? Or doesn't it matter? I am aso interested in NAS workflow, but assume that I won;t have the money to implement that yet as it means setting up a server and stuff. Just looking for some general advice on the nest way to go. I currently run 3 separate hard drives from my iMac (which has the software installed). 1 seagate USB 2 hard drives, which are used for archive, video footage and project files, the other is a Lacie firewire 400 connected via firewire which can go to 800, this drive is used for exporting/rendering, preview files and media cache. With this setup it's starting to clog and is really quite slow. Any advise is welcome and appreciated.
