[root@ff root]#  hdparm -tT /dev/sda

/dev/sda:
 Timing buffer-cache reads:   128 MB in  0.50 seconds =256.00 MB/sec
 Timing buffered disk reads:  64 MB in  1.38 seconds = 46.38 MB/sec


I think it's not very good, I called dell support (in France) and they 
didn't
found an answer about the poor performances.
