How much data will a DVD+R DL really hold?

[David9799]

7.95 is what vidoehelp says is that right?

I thought it would be more like 8.2

DVD-9, holds around 8 540 000 000 bytes and that is 7.95 computer GB.. Also called Single Sided Dual Layered. This media is called DVD-R9, DVD-R DL, DVD+R9, DVD+R DL or 8.5 GB Media.

* In the computer world is 1 KB data = 1024 bytes so 4 700 000 000 bytes / 1024 = 4 589 843KB / 1024 = 4482MB / 1024 = 4.37GB.

Extrapolating this, that means that you say that 7.999 GB is 7 GB and 999 MB, yet 8.0GB is, in fact, 7GB + 1024MB (1 GB), so where does the extra 25MB go ?



8,540,000,000 Bytes / 1024 = 8,339,843.75 KB

8,339,843.75 KB / 1024 = 8,144.38 MB

8,144.38 MB / 1024 = 7.95 GB

But even if the disc says 4.7GB, it really only is 4.37GB???!!!

see right above

* In the computer world is 1 KB data = 1024 bytes so 4 700 000 000 bytes / 1024 = 4 589 843KB / 1024 = 4482MB / 1024 = 4.37GB.
