Which is better a DVD +RW or a DVD -RW?

Which is better for long term storage, DVD+R/-R or +RW/-RW?

  • DVD+R/-R uses a coated die while DVD+RW/-RW used a phase change metallic material to hold date. I hear that the write once method will last about 5-10 years. But would a rewritable that uses a metallic phase change last longer in storage than one that uses a coated die process?

    DVD+R/-R—claims are up to 100 years RWs are much more fragile ... View this PDF for all the techno-chemo jargon : http://www.memorex.com/downloads/whitepapers/WhitePaper_Lifetime_Expectations_Optical_Discs_Mar06.pdf regards, Philip T

Currently, CD-RW discs can be rewritten approximately 1000 times. The unrecorded shelf life of a CD-R or CD-RW disc is conservatively estimated to be between 5 and 10 years. So,as you can see, there is no difference between the two types.

I would go with Rs The shelf life of the disks are about the same (Philip please read the paper you post), but the occurrance of an accident with a closed R is smaller. (someone may accidentally use one of your DVDs to record sometheing they need) Remember to also store a reader and software with your disks so they can be read in 50 years when the computer don't even know any more what IDE or DVDs are. (try reading a 5.25 floppy anyone?)

Don't look too close!
