Is anyone familiar with these?

I am thinking about buying one. It would primarily be used for backing up user files on my home office machine (I have around 4 gb of files/docs).

The one I'm looking at is a DVD-RAM/DVD-R combo from Panasonic (LF-D311). This is a little overkill for straight backups, but the DVD-R is supposed to allow mastering of DVDs you can play on a regular DVD player (I think). A neat little extra for some added flexibility.

Anyway, most of the stuff I've come across trying to research this is woefully outdated (I'm talking 2-3 *years*). So, anyone have any thoughts? Would this be a good daily backup solution for 5-10gb of data? Anything else out there? (another possibility I'm considering is the Iomega Peerless with 10 & 20gb cartridges... but the DVD solution, while smaller capacity, seems more versatile to me...)

PS: Oh, and for anyone who's used DVD-RAM, for the double-sided discs, does the drive read both sides or is it necessary to flip the disc?

Thanks for any advice!
