It is a trade-off between performance and security.


If you bundle your disks with lvm, you have the option of
striping, so you may gain performance, but AFAIK you loose 
ALL your data if only one of the disks goes down.

Of course, from that perspective, it would be good if vdr
would make an attempt to keep one recording on one disk.
I do not know if Klaus has made that change yet. At least
he has announced in the past that he will. 
At least the initial version of multi-disk support in vdr
would always put the next file on the emptiest disk, even
if there was a lot of room on the disk that contains the 
first file. As soon as Klaus changes that (if he has not
done so already), I believe there are clear advantages 
to the vdr-based solution compared with lvm.
