For working with DV harddrive performance is not much of an issue. DV is only 5mb sustained throughput. Most old 5400rpm eide drives can handle that. From what I have seen the 80GB western digital 7200 ata100 drives at $190 are the best deal in town. Since the software I plan on using (adobe) doesn't run on Linux I have no plans of dual booting. For cost and capability the promise card is exactly what I am looking for and I would use just raid 0, but I want a little redundance. With dv taking about 110mb for every minute of video if we try to render a feature lenght show with titles and credits (120 min) we will be looking at 130GB+ worth of files (not one file, but several) so we just need a lot of disk space and I don't want to loose everything from one drive going bad. Plus for the shorts we have been working on we average shooting 30 minutes of film for a 3 minute show. You end up with a lot of extra. SCSI is just way too expensive. Performance is not our top issue capacity is. Raid 0+1 is a waste of space for us. If you have a server that must be up 24x7 and have SUPER fast disk access then 0+1 is for you. We don't have that requirment. Raid 5 is a slight performance hit, but we only need to be able to sustain 5mb/s and that will be trivial with ata100 7200 rpm drives. We want to be able to have all our shots on disk so we can work them without going back and forth between the tape and the HDD. I will probally need to get a different power supply for the case, just because of all the drives, but I didn't realize that the tyan board needed a different power supply. We aren't planning on ordering a new monster system for a little while, but I plan ahead. For now we will just be using our ungraded PPros.
