Blu-ray disks, however, use a combination of silicon and copper which is bonded during the burning process, this alloy is much more resilient than the organic dye. Manufacturers claim a life span from 100 up to 150 years for Blu-ray disks.â. â = However, these media don't exist long enough yet to confirm or reject those claims. So at the moment, it's about as long as the oldest working DVD/BD is still working. These claims are made assuming the disks are stored properly.
A single-layer Blu-ray disc, which is roughly the same size as a DVD, can hold up to 27 GB of data-- that's more than two hours of high-definition video or about 13 hours of standard video. A double-layer Blu-ray disc can store up to 54 GB, enough to hold about 4.5 hours of high-definition video or more than 20 hours of standard video.
