What is the maximum amount of data a Blu-Ray Disc can have?
Blu-Ray is currently rated for 50 Gigabytes of data using a dual layer disc, single layer discs can hold 25 Gigabytes of information. Using a 25GB disc, that is 9 hours of HD video and 23 hours of ye olde fashioned SD (dvd) quality video. In laboratories, researchers have managed to squeeze hundreds of gigabytes on to a single Blu-Ray disc. But don’t expect to see anything like it on the store shelves anytime soon. Ooops. I mistook your question, corrected answer above: It all depends on the rotational speed of the drive 1x drives are rated at 36 MegaBITS per second (36 mb/s). 2x BD drives = 72 mb/s 8x drives are being planned and are expected to transfer data at 288 mb/s and a hypothetical 12x BD drive would read data at 400 mb/s MB- Megabytes mb- megabits Mega is the Greek prefix for million. Giga is the Greek prefix for billion. One byte is = 8 bits. One bit is a single 0 or 1. (Congratulations on being the first to post a question in the Blu-Ray category!
