1 TB optical discs on the way

I saw this and thought holy crap...that's a lot of room for roms and music!

Very interesting... I wonder how they account for vibrations, dealing with the layers at such a small scale?

Jouster:

Beats the heck outta me, but I like the part about it not being too different part-wise from what's in use now.  That means quicker adoption by manufacturers, cheaper prices and it gets to market quicker.  I could put my entire CD collection on one 1TB disc!  And I have over 250 CDs...and more mp3s on my laptop.  That would be pretty sweet for a long car ride.

Mind-boggling.

But one has to ask whether all of this increased storage actually makes data safer.  The more you put on one disc, the higher the data loss when something bad happens.  It will mean redundancy will become even more important.

It also didn't really speak of resistance to things like scratches or dirt, which will probably be compromised due to the higher bit-densities.

I have a full-height 1GB hard drive that has pretty much been on for about 10 years straight and it hasn't lost a byte.  But I can't seem to make an 80-gig last for more than a few years.

Exactly.  I've just about given up using optical media for backups.  They are just too unreliable -- a simple scratch or a few years of bit rot and some of your data is toast (if you have kids, you can certainly attest to this).  You either have to create par sets for everything or burn 2 or more copies.  Plus they are so slow.  HDs are so cheap now (just got a 500 gig for $99), I've started putting all my stuff on external drives and storing them on a shelf, instead of burning 120 DVDs.  Also this way I have one drive for emulation, one for music, etc.  When I need something, I just plug into my USB port.  It remains to be seen how well it will hold up in storage, but I can't imagine it would be any worse than optical media.
