michaelteo2000 Posted March 16, 2012 Share Posted March 16, 2012 I have a BackTrack 3, just wondering which is better if I decide to run it on a disk, CD or DVD ? Thank you. Link to comment Share on other sites More sharing options...
Shadowx Posted March 16, 2012 Share Posted March 16, 2012 CD is much faster because of the low disk space and fast read/write. Link to comment Share on other sites More sharing options...
nightwolf Posted March 16, 2012 Share Posted March 16, 2012 Yup that's true using a CD is much faster due to the low disk space when reading BackTrack 3 or any other version Link to comment Share on other sites More sharing options...

Psycho-gHo Posted March 16, 2012 Share Posted March 16, 2012 CD Speed: ````````````````►1X CD =150 KBps► 52X CD = 7,800 KBps / 1024 = 7.61 MBps DVD Speed: ``````````````````►1X DVD =1.35 MBps (1,350KBps).► 8X DVD = 10.80 MBps ► 16X DVD = 21.6 MBps ► 20X DVD = 27.0 MBps The data transfer rate from a DVD-ROM disc at 1x speed is roughly equivalent to a 9x CD-ROM drive (1x CD-ROM data transfer rate is 150 KB/s, or 0.146 MB/s). DVD physical spin rate is about 3 times faster than CD (that is, 1x DVD spin ~ 3x CD spin), but most DVD-ROM drives increase motor speed when reading CD-ROMs, achieving 12x or faster performance. A drive listed as "16x/40x" reads a DVD at 16 times normal, or a CD at 40 times normal. DVD-ROM drives are available in 1x, 2x, 4x, 4.8x, 5x, 6x, 8x, 10x, and 16x speeds, although they usually don't achieve sustained transfer at their full rating. The "max" in DVD and CD speed ratings means that the listed speed only applies when reading data at the outer edge of the disc, which moves faster. The average data rate is lower than the max rate. Most 1x DVD-ROM drives have a seek time of 85-200 ms and access time of 90-250 ms. Newer drives have seek times as low as 45 ms. ----- The data above is a little older, but still applies I believe. Saying that, the above responses would be drastically "wrong". Whose to say. Link to comment Share on other sites More sharing options...
rudrax Posted March 16, 2012 Share Posted March 16, 2012 Usually DVDs are usually found upto 8x and CDs are found upto 52x... :huh: Link to comment Share on other sites More sharing options...
michaelteo2000 Posted March 16, 2012 Author Share Posted March 16, 2012 That's mean a DVD transfer rate is much more faster than a CD ... ? Link to comment Share on other sites More sharing options...
Administrator DKT27 Posted March 16, 2012 Administrator Share Posted March 16, 2012 Yes, DVD transfer rates are faster than normal CDs. You guys should burn few DVDs. :) Link to comment Share on other sites More sharing options...

dcs18 Posted March 17, 2012 Share Posted March 17, 2012 Usually DVDs are usually found upto 8x and CDs are found upto 52x... :huh:That CDs are faster than DVDs is just another urban myth. The 8x speed of a DVD is much much higher than the 52x speed of a CD. Link to comment Share on other sites More sharing options...
