You'll need lots of disk space then. > You mentioned raid5. I've been meaning to study up on the different > raid setups but currently know zero about it. Why raid5?

Well, with your huge video files I guess you might reach about one TB a day during production phases... depending on the actual project size, of course, but a few hundred GB of video data can easily happen. And you might end up having huge files newly created / modified, that would end up in your 4hourly incrementals, I guess. > I do plan to either buy prebuilt/configured NAS which could be the > destination or create a linux home NAS with gentoo linux running as > many SATA discs as one OS can muster ... well something like 6-8 I > guess giving about 1 terabyte of space.

When using a NAS system you should also implement a second gigabit network between the SD and the storage server. > Long as we are at it maybe you have some suggestions about the NAS > stuff too.

I don't think speed is the most important thing to consider. Rather, look for something that has a history of running rock-stable, that has the necessary management capabilities - you really want to be notified of disk problems as soon as possible! - and that can be easily operated. For example, even if you are not available yourself, someone in your business must be able to deactivate a failing disk, to activate a spre disk, and to make sure the array is rebuilt. Using a shell on a linux system and calling the appropriate commands is definitely not something to be done by your average video operator :-) Also, make sure your RAID system allows hot-swapping of disks, which is not simple on a standard PC-based server. Otherwise, to swap a failing disk, you have to power-down your storage server. Using hot swapable systems, the process of swapping disks and recreating the array can be done during operations. It will affect speed, but things will continue. Finally, make sure you have enough spare disks available, and don't use cheap desktop disk.
