Yes it does. a DVD holds 4.7 gigabytes of data (1 gigabyte is 1000 megabytes), while a single layer Blu-Ray disc holds 25GBs of data. That is significantly larger than DVD.
I use a DIGISTOR(digistor.com) Blu-Ray burner to back up my files, and the 25GB is more than enough for all my back up needs.
A Bluray disc stores five times more data than a DVD. Therefore, a DVD will not have the capacity to store the contents of a Bluray disc.
CDs and DVDs share the same physical format but the DVD stores more data that a CD. It does this a much finer set of optical tracks on the disc than the CD has. In a similar way, Bluray discs hold far more data than a DVD.
A DVD can hold up to 50 GB of data.
Disc drives can hold more data than catridge drives.
No, that's with all the ps3 discs. Its called BLURAY. That's another distinctive feature that distinguishes it from the 360. Its more scratch resistance and holds more space.
A Bluray disc can store up to 50GB of data (the maximum storage size is not specified in the standard so data capacity may be higher in some discs. A CD will store approximately 700MB of data, about seventy minutes of stereo music in CD format. One Bluray disc should store the contents of at least 70 CDs. Because music CDs are rarely filled to capacity, in practice, it is likely that more than 70 will fit onto a single Bluray disc or about 83 hours of music. If CDs are converted into MP3 files, the data size can be reduced substantially. Using an MP3 data rate of 128KB, the data size is reduced by a factor of 10 so in excess of 830 hours of music can be stored on a single disc. 800 hours of music will last almost 5 weeks if played continuously and that should be enough for people even with the most varied musical tastes.
There are 16 layer single sided blu ray discs which have storage capacity of 512gb. That suggests at current abilities a 2 sided disc having capacity of over 1 terabyte. The research and tools for more levels is ongoing. As such it is likely that this will expand a good deal more than that (there is no physical reason why we couldnt double this many more times)
A dual-layer Blu-Ray disc can hold up to a maximum of 50 gigabytes, and that is 5 times more data than a dual-layer DVD can hold
Data is stored on the hard disc. The more memory hard disc has the more data can be stored.
CDs, DVDs and BluRay discs all work in similar ways. The primary difference is the data density on each disc. CD is the lowest density. A DVD can store several times the amount of data on the same surface area and BluRay will store several time the amount of a DVD.
A Blu-Ray disc can hold up to a maximum of 50 GB (5 times more data than a DVD can hold). Each movie consumes different data space
While they are physically very similar (thin metal layer encased in plastic); the primary difference is in the data storage encoded onto the disc. A BluRay disc is designed to hold a much larger amount of data storage in comparison to a DVD. Technically speaking even a CD is essentially the same physical concept, thin metal information disc protected by a layer of plastic. Each generation of disc encoding has resulted in around 5 to 10 times more data storage. Much like how DVDs are 5 to 10 times more storage than CD's, Blu Rays (and their now deceased cousin the HD-DVD) offer 5 to 10 times more storage capacity than DVDs. (the 5 to 10 times depends on whether a single layer or a dual layer is used) For movies of course this higher amount of data storage means that clearer pictures are achievable. In order to display higher definition images a larger number of pixels must be generated for every frame of the film, which greatly increases the size of the data file required to store the film.
