Thanks for your response. <br>The hardware I have now is not sufficient to set up a ramdisk (just 4 gb)... But memory is rather cheap nowadays. If i'd buf up the server with 8 extra gigs for use as a ramdrive, do you think that might be enough to record between 30-60 simultanious streams? Or should it be way more? <br>
<br>btw, I found this thread somewhere: <a href="http://lists.digium.com/pipermail/asterisk-users/2005-October/120930.html">http://lists.digium.com/pipermail/asterisk-users/2005-October/120930.html</a>, but this is rather old info. Is this documentation still usefull? And if not, do you happen to have any idea/url/doc where I can find a bit less old info?<br>

There are 2 issues i think, one is the seek time on harddisks and the<br>
lack of a big buffer in Asterisk (saving 10 streams at the same time<br>
will cause a loooot of random writes).<br>
The other one is the interrupts being taken up by the harddisk.<br>
<br>
So an SSD might help, saving to an network drive might help (it moves<br>
the issue to another server, where it might not cause a problem),<br>
buffering to ram (but you will lack space).<br>
The best solution depends on your exact hardware and the amount of<br>
writes you want to do.<br>
<br>
Buffering to a ramdrive before moving it over NFS seems like the best<br>
idea to me.<br>
