Computer Hard Drive Configuration

What is distributed parity? Why does raid 4 cause bottlenecks? How many disks for raid 4 raid 5?
So you got raid 4, drive A,a,a*. B,b,B*.C,c,c*. Suppose the are all 500GB, where is parity going and how big is this set up?

Looks like I need drive D for parity, but then I never considered a raid before, I thought that ram was the major thing that determines speed with graphics.

Colin,

The new generation of SSDs are much faster thean the best of the spinning drives, including the raptors and long estimated life spans.

RAM is the main consideration in editing performance, the aspect that fast HDDs gives you is that it can load/save files much faster.

Yes - I've had a chat with Sean offline about them. It seems that the older generation were a bit "toss a coin" when it came to performance -v- RAID 0 Raptors, but the new generation seem to have progressed quite nicely. Having said that though, I suspect that the new Raptors in a RAID 0 (with all the buffering and look-ahead caching that goes on) may in reality give an overall system performance for certain types of files thats "more than adequate".

I'm looking forward to trying one none-the-less though.
