Don’t bother calling me a Blu-ray hater because I have two BD burners and several more players for work. I have begun to wonder if that was a mistake. The cost of hard disk space is falling much faster than BD.

1TB disk <$100 ($0.10/GB reusable - $0.20/GB in RAID 0) so it’s cheaper to store it than to put it on Blu-ray at about $0.24/GB. Standard DVD cost about $0.04/GB, DVD-DL about $0.11/GB. Unless the cost is brought down very quickly, BD may never see wide spread adoption for anything but movies.

I am already finding increasing skepticism and resistance at professional conferences to the idea of it becoming a major data storage medium.

 

hah, you are such a blu-ray hater!  You bought your laptop without knowing it even had blu-ray.

Anyway, the cost of storing on a hard drive has always been cheaper than storing on optical media.  The point of having it on a disc is an increase in portability and insurrance that it won't go away when your hard drive dies.

No, actually that hasn't been and even today isn't true.

25x25GB BD/$300=$0.46/GB

100 x 700MB CD/$15 =$0.21/GB

25x8.5 DVD DL/$25=$0.12/GB

 

 

1TB HD/$100=$0.10/GB

800GB tape/ $35 = $0.04/GB

100x 4.7GB DVD/$21=$0.04/GB

Blu-ray is over 10x more expensive than DVD  and almost 5x more than HD server space. Not very attractive.And not very portable since so few use it.

As far as using optical media as"insurrance that it won't go away when your hard drive dies" , no thats actually what the RAID is for
