Drive Speed Question - Blu-ray Forum

slapshot6819 · 02-19-2009, 11:07 PM

What is the object of a 4x Blu-ray player vs. a 2x or 1x when it comes to watching movies on an HD TV? I mean, I understand that a the 4x would write faster, but how does it affect the ability to read data for movies? I am guessing that if I were using it on a computer to install some sort of program, the faster drive would install faster, but again... how does a faster drive effect movie playing?

Not movie playback DIRECTLY, but indirectly it helps. Firstly, BD has a memory buffer to store the data so that glitches can be re-read on a second/third pass; this buffer is also needed for PiP and BD-Live functionality. Secondly, drive speed helps when you want to skip a chapter or several chapters ahead.
