Default Good news for high volume data backup

http://www.timewarner.com/corp/newsr...700383,00.html

Warner chose to support only the higher capacity Blue Ray format (50GB
per disk for Blue Ray vs. 30GB per disk for HD DVD).

This could mean the death of the lower capacity HD DVD format and lower
costs for Blue Ray disks due to their mass use (economies of scale).

Good news for all photographers who have to backup Gigabytes and
Gigabytes of images :-)

Gave up on optical media when 500GB hard disks dropped to 100EURO or less.
Now I back up nearly instantly to removable drives.
If you install a RAID array, it's even simpler.

I'm considering whether I really want wallets and wallets of DVDs for
backup - DVDs which may not be readable in a few years time. Instead, I'm
thinking of a couple of portable 250GB 2.5-inch HDs......

Hmm. You might be right, but considering that HD DVD has some powerful
supporters, don't knock it out yet. I also am not sure optical disks
would make good backup media only because writing to them would be a
heck of a lot slower than mechanical disk drives or solid state devices.

I too assumed that the recent announcement that Warner had chosen BluRay
might mean the end of HD-DVD, but an article today says that consumers have
bought about 60% more HD-DVD machines than BluRay (something like 500,000+
to 300,000+). One of the reasons for those numbers may be that WalMart
sells HD-DVD machines exclusively.

In fact, this MIGHT be a very bad news to (smarter? ;-) consumers.

I happened to investigate the difference between two formats last
week; ignoring the size difference (which may come and go due to
possibility of multi-layer variants), the MAJOR difference between the
formats is the encryption.

Apparently, Blu-ray MANDATES the AACS encryption. To add AACS, you
need to set up an account with AACS (about $3K - $10K, depending on
nobody knows what), and, after this, pay AACS about $1500 for each
master disk. Currently, the state of debugging is that you need about
3 "try" masters before you get a satisfactory result. This gives the
minimum overhead price of AACS of $9K or more.

This is nothing for major releases; thus people who see HD contents
only via major movies, this overhead does not matter at all. But for
"independent" video producers, this makes releasing Blu-ray
prohibitive. Thus, a Blu-ray-only world would be skewed much more to
the side of big corporations.

[Today, to release a few thousand run costs about $3.5 per HD disk,
and $7 per disk on Blu-ray; AFAIK, this difference is due NOT to the
technical matters, but entirely to AACS fees (it is with a producer
who takes video content, and returns already printed stuff). It
won't go down due to volume economy. The printing price is
practically the same - both per layer, or per gigabyte...]

Hope this helps,
Ilya

P.S. I could not find out on which step the AACS-requirement is
enforced. Is it the player, the Sony printing facilities, or
ALL printint facilities? If somebody knows, please answer...

Thanks...
