1.5 How much data can you fit on a Blu-ray disc?

A single-layer disc can fit 23.3GB, 25GB or 27GB.
A dual-layer disc can fit 46.6GB, 50GB or 54GB.

To ensure that the Blu-ray Disc format is easily extendable (future-proof) it also includes support for multi-layer discs, which should allow the storage capacity to be increased to 100GB-200GB (25GB per layer) in the future simply by adding more layers to the discs.

1.7 How fast can you record a Blu-ray disc?

According to the Blu-ray Disc v1.0 specification, 1x speed will require a 36.5Mbps data transfer rate, which means it will take about 1 hour and 33 minutes to record 25GB. The Blu-ray Disc Association are currently working on the v2.0 specification, which will support 2x speed to cut the time it takes to copy content from one disc to another in half. In the future, the data transfer rate is expected to be raised to 8x or more.

1 and a half hour for the "smaller" discs, thats long. and its like if history is repeating, i remember when the first cd burner came out with 2x speeds.

8x would mean reading 36.5 mbytes/sec off hdd. better make sure you defrag before burning

And? It's much bigger than any other optical disc we have.

When CD first started it was at 1x (1x = 1.41Mbps or 0.18MB/s)
When DVD first started it was at 1x/2x (-) and 2.4x (+). (1x = 11.08Mbps or 1.39MB/s)
When Blu Ray will first start it will be 1x/2x. (1x = 36.50Mbps or 4.56MB/s)

2x Blu-Ray = 6.59x DVD = 51.73x CD (52x is maximum CD rotational speed reached)
At 4.9x, Blu-Ray would be faster than any DVD can spin (16x).

Blu-Ray will eventually greatly surpass DVD speeds just as DVD greatly surpassed CD speeds.

Are all the discs RW? Or how are they doing this? The archival possibilities of this has me drooling.

Yeah, anything too much above 8x and HDD's will start to be the bottleneck.

actually, wouldn't 36mbyte/s already be a bottle neck for most people? can typical hdd sustain that speed for 15 minutes?

Most the newer 7200 rpm drives can sustain 60 MB/s and fade to 35-40 MB/s so it won't be that big of a problem. Also we should be getting newer faster 10,000 rpm drives before bluRay ever hits 8x and I bet many of you will upgrade your hard drives.

PS: There is always RAID :)
