On my pc I get:
/dev/hda:
 Timing buffer-cache reads:   128 MB in  1.73 seconds = 73.99 MB/sec
 Timing buffered disk reads:  64 MB in  2.98 seconds = 21.48 MB/sec

On my laptop I get
/dev/hda:
 Timing buffer-cache reads:   596 MB in  2.01 seconds = 296.52 MB/sec
 Timing buffered disk reads:   54 MB in  3.05 seconds =  17.70 MB/sec

On other raid server I have on production I get
/dev/hda:
 Timing buffer-cache reads:   128 MB in  0.24 seconds =533.33 MB/sec
 Timing buffered disk reads:  64 MB in  1.29 seconds = 49.61 MB/sec

Which "line" should be "at least 45MB/sec"? I read the man page for -tT opt
but I know too little of how it works to really understand it.
