Dual Layer DVD Max. Capacity...

[mitchelt]

Hi:

I want to make sure I got this straight, a Dual Layer DVD can hold 8.5Gig if used with a DVD Burner that is dual compatible.

My question is can it actually store a single 8Gig file, or is it 4Gig on each side...I sure hope that question is not as silly as it sounds?

The reason I ask is that I am wanting to purchase a HD Camcorder that stores to SD Cards and I wanted to stick with an 8Gig SD card so I could easily backup the whole thing to a DVD for safe keeping. Now the chances of filling an entire 8GB SD card in one shooting is slim, I just want to make sure.

Thanks!

Mitch

Dual layer discs are single sided. Actual recording capacity is around 7.9GB. If this is important video I would consider using something like a hard drive along with the DVD for backup.

Thanks for the info!

This is very important video, it will be of my little girl growing up. Seeing that DVD's are cheap I plan on making two copies, one for the house and one for the safety deposit box in the bank.

I wouldn't just trust DVD-r's, depending on how good the burn was, you may end up with a rude surprise in a few years.

http://www.quickpar.org.uk/ has a nice utility to make par2 recovery files, which I would use on important data.
