[LRflex] Re: 500gb discs?

Hi Spencer!


I wonder, too ... but then DVD's have proved a more reliable medium
than CD's for archival storage.  Time will tell.


I haven't looked at the physical structure of a writable DVD but if it
is the same a writable CD, then scratching the "top" side will destroy
a DVD as easily as a CD.
Actually, Spencer, that's not quite true. The DVD's have an extra (albeit thin) layer of plastic between the data an the "top" side.. which makes them more resistant to damage than a CD. Otherwise, they are, indeed, much the same.
I don't think the technology between the 2 is different enough for me to say one will be more reliable than the 
other. I treat both as unsuitable for archival storage.
That is, of course, your choice. These days, none of the options are foolproof. Although I've had my problems with 1 set of DVDs, I've not lost any photos. I use DVDs, for back-up, simply because I've also had hard drives fail, and with a DVD "going west", I will lose fewer photos than if a HD "goes west". I also burn 3 copies of each disc!
