List of HD data rates?

Hello,

I'm still working in SD, but I'm planning to start shooting HD in the near future. I'm currently rebuilding my data architecture, and I'm trying to do that with the future in mind.

My question: Does anyone have a comprehensive list of all the different HD codecs and their data rates? I don't know what type of HD I will be shooting, and I'd like to have my bases covered, or at least have an idea of where I stand.

I think I'm going to build a Linux server with 3-6 RAIDed drives, and I want to know what kinds of data rates I should be shooting for.

Thanks!

I'm not sure how data rates will help you as editing performance is dependent on the codec's architecture. For example DVCPROHD has a 100 mbps data rate but it's much more easily edited than HDV which is only 25 mbps because it's intraframe instead of GOP. On the other spectrum AVCHD has a max data rate of 24 mbps but it requires way more processing power than HDV.
 
AVCHD - 6 to 24mbps
HDV 720p - 19mbps
HDV 1080 - 25mbps

DVCPRO-HD - 40 to 100mbps (depending on 720pN or not)

AVC-Intra - 50 to 100mbps

XDCAM-HD - 18, 25, or 35mbps

XDCAM-EX - 25 or 35mbps

XDCAM MPEG422 - 50mbps

HDCAM - 140mbps, but you can't edit it natively
HDCAM SR - 440mbps to 880mbps
HDD5 - 270(?) mbps

Then there's the editing codecs like DNxHD, ProRes, and CanopusHQ, which range from about 140mbps to 220mbps or so.

Does anyone know Native Redcode? Im having hard drive speed issues at the moment, hoping that an eSata card and drive will solve it.

Why does there have to be so many?

Easy - So companies can make money. If Panasonic uses it's own codec (DVCPRO-HD or AVC-Intra), you pretty much have to buy other Panasonic stuff to go with it or use gear made for it. If everyone has the same codec, you get multiple companies with the same accessories, then it comes down to a lower price war. It's ALWAYS about making money. That's what they're in business for. If you were in business, wouldn't you do the same thing? People buy your camera, they have to buy your cards, decks, accessories, etc. at the prices you set. They'll be some companies that pop up that can handle your codec, but they have to have your permission to use it, which = more money.
