any solution? or tips?
thx

You're misreading the result: that's 30 MByte/s or 240 Mbit/s. Given that your MBP only has USB2 ports, with a theoretical max. data rate of 480 Mb/s, that is not abnormally slow.
you're right
but i've tried this hdd on windows 7 machine with core 2 duo and mobo asus p5k-e which is 6-7 year old
and there 10mb/s plus on read/write --> 42 mb/s read 35 mb/s write
Another factor is the internal drive of the MBP: that is probably quite slow compared to the drive in a desktop.
actually it doesn't matter, but anyway i'm using ssd samsung + hdd = fusion drive
