CD/DVD cach

Hii, I have a small question about caching in linux.
Can I make my system cache more every time I access the CD ?
I mean, it could really speed up my CD if I could get 2 mega each time instedd of 512kb or something.
Is it possible and if so, How can I do it?

Re: CD/DVD cach

You can tune the read-ahead to 2Mb with

hdparm -a 4096 /dev/hdc 

assuming /dev/hdc is your cd drive. (4096 is the number of 512-byte sectors, the default seems to be 256.)

Don't expect any miraculous performance gains, though.

Re: CD/DVD cach

I noticed that when I access data on my DVD-ROM, it gets cached automatically, e.g. when I watch a few episodes I burnt and afterwards I copy them to disk, I get ridiculous speeds (~ 30MB / sec).
