Read Rate Data Speeds and CPU questions...

[RubenS]

Hi,

 

I have a few questions about ripping speeds or the Read Write speed.

 

I noticed that when I rip DVDs to .ISO files they sometimes start slow and then eventually work their way up to a faster rate. Some DVDs start at a Read Rate: 5.5 K/bps (3.5x) and then get up to 12 or more 1/2 through the rip. Then other DVDs start off faster Read Rate: 12 K/bps (3.5x) and go up to 24 K/bps Why is this?

 

Does the CPU/Ram/Hard Drive Speed play any part in the ripping speeds? When I open task manager while ripping I notice that the CPU is only around 5% and Ram doesn't seem to change much.

 

What does the (3.5x) mean in the read rate? i.e. Read Rate: 12.5 K/bps (3.5x)

Does this mean the DVD is ripping 3.5x times faster than real time?

 

Thanks in advance!

 

Ruben

This isn't the DVD Decrypter forum. Are you sure you're in the right place?

The disk doesnt have to to spin as fast on the outer part of the disk(think about it same number of revolutions but more data is going by) so it appears faster once it gets to the end.
