That's not much, AFAIR just sufficient.

Is here someone recording "VDRs record of slowest CPUs" ;-) ?)
(on a web page)

What IDE mode? (hdparm)

Reiser is good for many small files, VDR has only few but big.
Use ext3 or better XFS

Change the default format paramters (at lest od ext3) to
fit the requirements.
Ext3 will reserve hundert thousands of file entries you
will never need on VDR.

verified? (becuse i just foudn a slowwww PC which "forgets" 
DMA mode on reach reboot/powerup.

what does "hdparm -t" say?
