Blu-ray is slowwww...

[TurtleMan]

I just read that the new BD's are only burnable at 2X speeds. It takes me between five-six minutes to burn 4 gig of data at 16X, so the blu-ray will take about 45 minutes to do the same. And since the new high capacity BD's are 50 gig, it will take something like nine hours to burn a full BD-R.

I'm excited about the higher storage capacity of the BD-R's, but 2X burns? I think I'm going to wait and see what the second-generation devices can do

CD Burners and DVD Burners burned slow too when they first came out.

I am sure it will get faster.

Hmm, it's wierd when it realting disk density to access speeds, but keep in mind that blu-ray and HD disks will have 10 times the capacity of a dual layer DVD. You can't really expect recorders for these new formats to be very fast since the equipment needs to be more precise. With such an increase in density, I'd imagine these burners will take a while to get faster. I'd hate to think of what a blu-ray burner will cost anyway. A 300gb USB HD will be cheaper and faster!

likely the burners will be $40 after a couple years. the discs will probably be $4 a piece

2X of what though? Are you sure that Blu-Ray uses the same speed scale as DVD? Don't know either way, just asking -- remember that 1X in a DVD drive is roughly the same data transfer rate as 16X in a CD drive.

How fast can you read/write data on a Blu-ray disc?

According to the Blu-ray Disc specification, 1x speed is defined as 36Mbps. However, as BD-ROM movies will require a 54Mbps data transfer rate the minimum speed we're expecting to see is 2x (72Mbps). Blu-ray also has the potential for much higher speeds, as a result of the larger numerical aperture (NA) adopted by Blu-ray Disc. The large NA value effectively means that Blu-ray will require less recording power and lower disc rotation speed than DVD and HD-DVD to achieve the same data transfer rate. While the media itself limited the recording speed in the past, the only limiting factor for Blu-ray is the capacity of the hardware. If we assume a maximum disc rotation speed of 10,000 RPM, then 12x at the outer diameter should be possible (about 400Mbps). This is why the Blu-ray Disc Association (BDA) already has plans to raise the speed to 8x (288Mbps) or more in the future.

will be interesting to see what format overall is better for data discs. this will include speed, error rates, general quality of the discs from their respective formats. the capacity we know is in blu-ray's hands....

lol this is the type of media supposed to be used in the playstation 3, slow speeds, that could mean slow loading times correct?

[krupted]

its sony, you can bet on it

One would hope that since they went back the drawing board on optical tech, that they would also improve access speeds along with increased density. I'd hope that HD and BluRay drives will make good use of SATA II.

hahah...it'll deffinetly cost sony some $$$ if it takes almost 10hrs to create a game

I read in a computer mag recently, they tested a BluRay drive and it used the IDE port. Yes it was only 1 drive and hope future models take advantage of SATA II.
