I've gotten to a point on my new 750GB iMac, where I need significantly more storage for video editing. I've determined that a consumer-level RAID device will best suite my needs for speed and redundancy (as opposed to a regular external HD and/or a server grade device/second computer). However, I've also determined, due to the unwieldily size of these machines, that I would really like to have the RAID device hooked up over the network (as a NAS) so it wasn't cluttering up my new desk. My question is this... if I go with something like the Drobo with DroboShare or a really any external RAID HD system (such as the WD MyBook World II) hooked up to an Airport Extreme Base Station, will I get the speed that I need from the drive to upload video content, edit that content, and export it, without any significant (or even annoying) speed reductions due to the network? My guess would be "NO" and that anything connected to the network won't be fast enough... but I wanted to make sure and check with you guys and your experience first. If any of you out there are currently editing your videos in this way... please share your experiences. What is your bottleneck? I am hoping it isn't the network speed, but I have a sneaky suspicion that it is... any real-world advice would be much appreciated. Also, what about HD video content? That can't possibly be fast enough over NAS, right?
