Panasonic LF-D521U DVD burner II

Summary: What is often overlooked is the 9.4GB capacity per disc due to the use of both sides. Another ignored factor is the protective cartridge - how much is your data worth? Naked media will never be as safe as cartridge based media. DVD-RAM is a block addressable type of media - you can go to head and sector meaning you can write as much or as little data you want as well as modify or delete it easily. The DVD-+RW/DVD-RW issue is overblown - independant studies (published in eMedia) show that both formats have about the same compatibility with DVD players.
