There just isn't a need to create a DVD drive with a modern, high speed data transfer interconnect because it's a dying technology and it's fastest transfer rate doesn't even begin to exceed what is already backwards compatible with USB 3.0ġ Wikipedia Modern compact discs support a writing speed of 52X and higher, with some modern DVDs supporting speeds of 16X.Ģ Wikipedia USB 2.0 was released in April 2000, adding a higher maximum signaling rate of 480 Mbit/s (High Speed or High Bandwidth), in addition to the USB 1.x Full Speed signaling rate of 12 Mbit/s. USB 2.0's transfer speed is 280Mb/s or about 35MB/s 2 so even the theoretical fastest DVD drive that you will ever find is less than the max limit of a USB 2.0 connection which, for all intents and purposes, has been obsolete since the beginning of 2009 (USB 3.0). The base write speed is 1x and a 1x speed is 1.32Mb/s so a 24x unit is about 31Mb/s. To understand why, we have to understand that the fastest DVD you will find is a 24x unit most will be 16x. You won't find a Thunderbolt 1 (much less and Thunderbolt 2/3) to an external DVD drive because there simply isn't any need to create one as USB 2.0 has more than enough bandwidth to accommodate even the fastest DVD drives on the market.
