My PC's full again - one of my hobbies is shooting timelapse sequences the trouble is they eat data space. A typical sequence takes around 16gb as raw files plus all the intermediate processing space. I cannot delete the raw data when I'm done - I've sold some stuff and the raw files are my proof that I did the work. I've been buying USB hard drives - 500gb and now 1tb but they're expensive and fill up quickly when I do several sequences a week, plus they take up quite a lot of space and it's no longer practical to do the secure thing of one copy at home and one elsewhere. So I've been wondering about tape drives but it seems there's a choice - cheap tapes and a stupidly expensive drive or cheap drive and tapes almost as much as a hard drive. Any other options? Aside from starting a server farm? I suppose I could just sell some of the cameras - it'd slow me down.
