If 54 MB/s decent performance? (Output from hdparm -t)

I realise the best way to increase performance is to have more than one
drive, even without RAID. I briefly had my home partition on a different
drive, and the system was noticeably faster. However, my main aim is to
make my system as quiet as possible, so two drives isn't the best solution!

I was just curious as to why the log showed those messages about ATA/133!
