Can someone (preferably) who owns a Verbatim BDXL 100GB (M-disc) - share with me how much actual data can you fit in that disc? I am not talking the advertised "100" gigs, nor a conversion from online conversion tools. I know that manufacturer perceive disk space differently, but what I m looking here is an actual size (e.g. in bytes) of how much usable data can you actually fit in one of those discs. That's total clean, usage size - minus any restrictions imposed/reserved by the disc. For example, in a 4.7GB DVD disc, I remember I could fit 4482MB of actual data. But what about that particular Verbatim BDXL disc?
