    Re: News - Buffalo and Pioneer prepare to launch BDXL drives

    Am I the only one who thinks that speed ratings of drives are unnecessarily convoluted and give no real information? For example, why should 24xCD speed be slower than 8xDVD speed? From the perspective of the consumer, anyway. It's nutty. And I have no idea what 2x speed on BDXL means, or even if it's faster or slower than on regular BDs.

    I totally agree! I have no idea what it means for BD, DVD or CD, other than what is 'fast'.

    At the same time, would transfer speeds be much better? I think that would probably just confuse consumers more. I can't really think of a good system for displaying speeds.

    Re: News - Buffalo and Pioneer prepare to launch BDXL drives

    I disagree with you two

    It's perfectly logical in my opinion. 1x CD was the speed it needed to spin to read 16bit 44khz audio off a disk. Now that is about 178kbytes/sec. Once you include all the error correction they added to enable reliable data storage on a CD, it goes down to about 150kbytes/sec. So a 24xCD is 24x 150kbytes/sec or 3,600KB/sec.

    DVD has the same principal. 1x DVD is the speed the disk needs to spin to handle the full DVD-Video spec. which is just over 1.38MB/sec. Unlike with CDs where the CD audio is written to the disk in a different way to data, DVD is just data dumped on a disk, so the data transfer rate is the same as the "media" transfer rate.

    BluRay is a little different in that 1x BD is the maximum data rate for the initial spec of BluRay format footage, this is 36Mbit or 4.5MB/sec. However, movies can now use up to 54mbit datarates for multiple video and audio streams. They can do this because stand along BluRay players have a lot more in common with a general purpose computer than DVD players ever did, so the standard can be updated a lot more easily as technology changes. Also it means manufacturers can sell replacement updated unit more easily.

    Now, what is rather stupid is the speed multiples flash memory card manufacturers insist on slapping across their cards. "600x CompactFlash" for example, it really doesn't make much sense. When you see that they are comparing their tranfer speeds to old CD drives, so that's where they get their measurement from, it would be much better if they just did the same as SanDisk with their Extreme series of cards and actually stated the minimum transfer speeds instead.

    Because remembering the base rates for different media and then multiplying them in your head is more convenient than having the actual value presented to you?

    you got done, Funkstar

    I ROFL'd.

    Oh, but thanks for the tutorial nonetheless. It will go in my 'useful facts' section of brain.
