I'm having a RAID-0 today with two 10000 rpm hard drives. It allows me to stream two video tracks for a long dissolve without a loss in FPS. That's when I use 960x540 size uncompressed AVI. Or Sonys MXF at 1920x1080. Not with Cineform.
Now lets say I want to use uncompressed AVI at 1920x1080 only. that is I want to play 2 or 3 streams of 1920x1080 at 29.97 fps with no FPS drop off.
------------------------------------------------
I've heard of some new Hitachi drives with 3 internal disks that apparently should have perfromance better than the WD 10000 rpm drives. Any info on this as to how it works in video streaming?
Intels PC Express card SATA card controller where you can add up to 8 SATA drives. Anyone with experiences on this?
-------------------------------------------------
The idea of having a SATA card with 8 connectors for 8 drives in a RAID setup sounds pretty attractive. Let's say 2 drives gives you speed enough for 2 streams, but for some reason you want to get even better performance - just add 2 more drives, or 6 more drives and apparently you would get magnificent streaming performance.
Now does this work well in real life? Anyone?
I can see the need for an efficient codec like MXF if working on a laptop, then rendering from the MXF's or when replacing with full size AVI's. But when working with a desktop PC, where there is the real ophyscial possiblity of adding the drioves needed - it really isn't desirable to introduce file space saving codecs at all is it...? Just uncompressed AVI and nothing else would be the best wouldn't it?
------------------------
So if you want, please let's discuss in this thread how we can set up truly efficient disk streaming with the right controller cards (if any) and the best disks. 4 disk setups etc.. So that the 1920x1080 files can be streamed smoothly and effortlessly and allow the CPU to do realy work instead of decoding quality degrading codecs etc.
