I have a VIA chipset and these are my hdparm results:

[root at mythtvbe ~]# hdparm -tT /dev/hda

Timing cached reads:   1208 MB in  2.00 seconds = 603.10 MB/sec
Timing buffered disk reads:  192 MB in  3.02 seconds =  63.61 MB/sec

Are the cached reads too slow? I've seen others post numbers twice as
large. My SD recordings are mostly good. I don't do HD with this
