G4 and V3

[dannyb]

I've been running testing on the G4s in Austin. They seem to be holding up quite well. The biggest issue is still hard drive. I added a Raptor drive to mine and it helped quite a bit. That setup got it as close as I could to the G5 model. I would like to say I could get you more results but that won't be possible since I have no more G4s to test with.

My biggest response to you would be to add a good secondary drive to the system. Keep the operating system and Catalyst/PixelMad software on the current drive and use the secondary drive for content only. That setup has sped up the performance here. It the same basic setup I've been looking at for months. It works very well. You will just have to get a good second drive. It needs to be at least a 10K rpm drive. Most below that just don't have the performance.

Hope this helps.

can you show a picture of how you installed your sata drive inside a computer with no sata support?

I've had a 1.25Ghz DP G4 up against my G5. Very similar performance.
The important things here are, as Danny states: Get a decent drive for your media.
10K SCSI drive or something.
Run the latest version of Mac OS X.3.
Get yourself a Radeon 9800.

disc drives are the limit to performance. and it is not the headline data rate. no IDE drives are good enough. And that includes all current firewire drives.
If you can get a SATA raptor inside an external firewire 800 case - then that would probably help.
Such things are just coming onto the market.
And will help if you are planning on using a laptop.

The latest generation of scsi 10k Atlas iV drives need to be used. or Western digital raptors.
Non-raid works better. and keep the operating system separate.

The G5 helps long term timing stability - which means your files will playback more accurately over longer time periods. And it helps with more processor intensive codecs, like photo jpeg and pixlet.
It also helps when you are using larger image sizes like 720p and 1080p.

But for standard dv file playback in non-critical timing applications - the main bottleneck is in the disc drives.
