fredklein writes "I recently started contractor work at a relatively small video conversion business. They accept jobs from the public as well as various photo studios and photo labs. They digitize everything from photos to VHS to old reel-to-reel film, putting it on DVDs. However, in the process, they end up with at least two DVDs to archive- one of the raw video, one of the edited. I'd like to move them to a completely hard drive based system, where the incoming jobs are saved right to video files, edited, then stored, all without being burned to DVD (except for the customer's copy). This, of course, requires massive amounts of storage. 20 jobs a day, roughly 5Gig for the 'raw' video (DVDs are 4.7Gig, but...fudge factor), another 5Gig for the edited, means about a Terabyte a week to store, or 50+ Terabytes per year. And that's not mentioning backups. I'm looking for any ideas on how to handle such a huge amount of video data, preferably while keeping costs at or below what the original DVDRs would have cost."
