Hi,
As mentioned above, the RAID isn’t gonna do a whole lot for speed. You might get tiny benefits from using it for your scratch disc as well as file access times. If you are doing work in HD then it may be necessary if for no other reason than to be able to see your animations play back in real time.
You can get pretty inexpensive RAID setup if you are not too concerned about losing data if a drive fails. I use a couple of Burley Port Multiplier boxes and a CalDigit eSATA controller for a JBOD and a RAID setup. These can be found at https://www.macgurus.com/
As for Nucleo Pro, obviously if you only have a single processor, it ain’t gonna help too much. With more cores plus memory, you get a really good performance boost. The nice thing is that when you send a render job to it, the background render works in “nice” mode (at least on OS-X). What this means is that if your foreground process needs the processors, the background will be nice and scale back while you are working. Yes, this slows down the background render, but it means that the system is still responsive in the foreground. And of course if you pause to get a cup of coffee, the background renders will speed up again.
Also if your work flow requires getting an animation to an editor in the next bay while you still need to continue on another animation, Nucleo Pro will let you keep working. (Yes, you could fire up the command line renderer, but this is easier.) If you tend to build the animations and then render over-night, then maybe Nucleo isn’t going to help you too much, but in my case it has been very helpful.
My opinion is that Nucleo Pro is the best plug-in I have bought for AE (and I have plenty of pretty good plugins.)
If you need to speed up your renders, you may want to look into adding memory. I currently have 2Gigs per core and that seems to be working pretty well for me since AE cannot access more than 3Gigs per core in a background render. I could still add more memory, but looking at the processor and memory load during renders, I don’t think it would help to go beyond 2 per core.
Hope this helps,
Lars
