Blu-ray all the way.

Forget everything else. Bigger capacities win for me.

Awesome, totally awesome. Now if they make writeable Blu-Ray drives, I can back up my whole HD on one disc :-D

Wow... imagine that... my whole hard drive on one disc... and I remember when 80mb was absolutely enormous and groundbreaking when I installed it in my LcIII! :eek:

It's amazing where technology takes us isn't it? Hi-Def will demand all the space it can get. My first HD was 30MB :eek:

ditto. thats the way things are these days, isn't it?

so forget my dual 1TB hard drives in my 3.5gz pbg5 for 2009.. ill just get two of these burners and a ******** of disks (which at the time will be around $.25 apiece)

These will be incredible for use as backup devices.

Right now, I'm making my backups to an Exabyte VXA-1 tape drive. The drive is expensive (I paid $800 for the external FireWire model, MSRP is $1000). Blank tapes are expensive (about $60 for a 170m tape that holds 33GB). Backup speed (according to Retrospect) is about 150M/min (or 20Mbps).

These 2x BluRay discs change all that. I'm sure the drives will cost a lot less than $800 (probably intro at around $500 and come down to under $200 a year or two later.) With 50G on 2-layer media or 100G on 4-layer media, the capacity is greater. I'm certain the blank discs will cost much less than $60 each - probably around $15 each at retail introduction and below $5 a few years later. And the speed is much greater (peak speed of 72Mbps. Figure something more like 50Mbps real-world, which is about 375M/min.)

This also translates to much more convenience. Right now, everything I own comprises about 60G - meaning I need two tapes to make a full backup. I have to remember that after the first tape fills up (usually in 3-4 hours) I have to insert the next tape. And then I need to swap tapes again when the program verifies the backup. With 100G (uncompressed) on a single disc, that's no longer an issue - I can start the backup and go do something else, because it won't need a second piece of media.

They should bring back the Laserdisc form factor. Imagine storing 2TB on those puppies.

From what I've read so far, the new four-layer Blu-Ray will be a recordable format. So, like, yay.
