message: the page states that the theoretical maximum of reading would be around 12x because any faster the disc would wobble too much to be read properly. I think that's a practical and not a theoretical limit.  —Preceding unsigned comment added by 88.0.142.204 (talk) 22:20, 13 January 2008 (UTC)
replies: text: It's a theoretical limit because no one has actually made a 12x drive Nil Einne (talk) 09:07, 17 February 2008 (UTC)

text: People out there try to guess when BD-RE 4x will get out. Why isn't it there? Is there a theoretical limit as well? Is it - as the missing 4x variant shows - lower than for BD-R?  —Preceding unsigned comment added by 212.149.48.43 (talk) 17:43, 17 July 2009 (UTC)

message: Where do I find out the max file size that can be burned? I'm sick of rarring huge files into chunks to burn on DVD-R -- with the max 2G filesize. Not having to do that would be a big reason for me to switch despite the triple-per-byte blank media cost... ClintJCL (talk) 02:28, 11 December 2009 (UTC)
replies: text: I've just been trying to figure this out.  I can't find information on the web.  Writing a single file the size of the free space reported by Windows (47332mb exactly) doesn't work; when you come to burn, Windows says the burn requires 48.9 GB.  That's not useful, since it's rounded off.  Toby Douglass (talk) 21:28, 17 May 2010 (UTC)

text: The max file size is calculated no differently than for a CD or DVD - it is a function of the file system used when authoring and capacity of the media. Using the UDF 2.50 format when writing backup files to BD media yields a max single file size of 16EB; well beyond the capacity of any media you will be using. I don't think this information would be particularly valuable in this article as it has nothing to do with the media itself - rather the manner in which information is recorded to the media.

replies: text: I don't believe pricing is relevant here - choosing one vendor isn't indicative of all market, and price changes frequently.  —Preceding unsigned comment added by 12.6.90.3 (talk) 20:54, 9 December 2010 (UTC)

message: see blu-ray no-fee specification 2012
the speeds given on the page are based on the speed of the hard drive reading the data, not the blu-ray media actual speed. the actual 1x speed is 36MB/s.
you can multiply for 2x to get 72MB/S etc. Blu-ray specification organization probably erroneously uses SI units instead of IEC units in their specification. and I suspect that since the disc industry uses GiB for disc data sizes, you should probably also use (?) MiB for the speed, since Microsoft typically also uses MiB and labels it as MB, etc., a lot of the industry does this (like with RAM, SSD's etc)...
so 
* 1x=36MiB/s×1=36MiB/s
* 2x=36MiB/s×2=72MiB/s
* 3x=36MiB/s×3=108MiB/s
* 4x=36MiB/s×4=144MiB/s
* 6x=36MiB/s×6=216MiB/s
* 8x=36MiB/s×8=288MiB/s
* 10x=36MiB/s×10=360MiB/s
* 12x=36MiB/s×12=432MiB/s
* 14x=36MiB/s×14=504MiB/s
* 16x=36MiB/s×16=576MiB/s
* 18x=36MiB/s×18=648MiB/s
* 20x=36MiB/s×20=720MiB/s
and so on. also, for those who don't know the difference between IEC (computer units) and SI units, I wrote a web page which shows the differences. SI and IEC Units compared side-by-side see also the web page on IEC unit specification IEC unit definitions: The binary prefixes .
