Again, I think you are searching in the wrong direction. Your 'hdparm
-tT' results clearly showed that the great difference between your
servers doesn't lie in hard disk performance (48 to 43 MB/s), but in
Memory/CPU performance (278 to 58 MB/s). When doing the same SQL query
several times the hard disk shouldn't be bothered much anyway since
either MySQL or aŽt least Linux itself should have cached the data.
