First off, a calrification: I am talking about a "regular" DL: disk, not a Blu-Ray disk.
The capacity printed on the disk is 8.5 Gb, but some of this goes to overheads and formatting information. The useable space is more like 8.2 Gb, and can vary depending on the data being stored, e.g. movies versus data.
8.5 GB raw, but closer to 8.1-8.3 usable after formatting, etc.
8.5 but you can only write 7.9 on the disk
8.5 GB wrong a double-sided, double layer DVD can hold 17 GB of data
So far, there isn't a double-sided Blu-Ray disc yet. But a double-layered disc can hold up a maximum of 50 GB (5 times more than a double-layered DVD)
8.5 GB
4gb+
8.9 GB :)
17 GB
about 7GB
4.8 gb
4.7GB on a standard DVD - can be a duel layer disk (double sided) which holds 9.4GB
Each side can hold a maximum of 50GB, so a double-sided can hold up to 100GB, but there haven't been any double-sided Blu-Rays yet
A single-sided, single layer DVD can hold 4.7GB of data, whereas a single-sided, dual-layer can hold 8.5GB. Double-sided, single-layer holds 9.4GB and double-sided, dual-layer holds 17.1GB. So anyone of these combinations can hold a 4.7 ISO image although the single-sided, single-layer may be a tight fit. I would use the single-sided, dual-layer and you won't have any problem. An ISO is simply an exact duplicate of someting (like a Linux operating system) so you will be ok. Hope this helps.
25GB single layer, 50GB double layer
Depending on the DVD you may have: 4.7 GB (single-sided, single-layer - common) (Two hours of high quality video) 8.5-8.7 GB (single-sided, double-layer) (3.5 hours of high quality video) 9.4 GB (double-sided, single-layer) (4 hours of high quality video) 17.08 GB (double-sided, double-layer - rare) (8 hours of high quality video) Double sided disks can be written on both sides, which is why they hold about twice as much.
DVD SizesThe most common DVD type is DVD-5 (1 side, 1 layer) having 4.7GB of storage. Double-sided DVDs are rarely used.

find it out on ur way i ain't gunna do da work for u to take it to skool
25 GB for single layer 50 GB for double layer
A single DVD is capable of holding 4813 megabytes of data. Blu Ray disks, on the other hand, can hold 25600mb.
