How much storage do Mini-DV files take up?

Have you ever wondered how much storage is required for mini-dv footage? In today's world, it's not as much as you might think.

Mini-DV requires approximately 1 gigabyte of storage for every 5 minutes. This may sound like a lot. But consider this, the typical retail cost of a 250 gigabyte hard-drive costs around $150.00. This means for $150.00 you can hold roughly 1250 minutes of dv storage, or 20 hours of media.

Think about this. It may be cheaper to archive all of your DV media on a hard-drive instead of tape. Hour long DV tapes can cost as much as $10.00 per tape. To give you an idea of how far hard-disk technology has advanced, take a look at this old 9 gig hard-drive that used to cost as much as $10,000. This was the price 10 years ago!
