Getting much faster speeds than you, something is definitely off with your drive or setup around it.
These speeds look about right for a Sata 2 controller. If its an old sata 2 board then your done. If its a newer sata 3 board make sure you have the ssd plugged into the correct port. Then check to see if AHCI is enabled in the bios.
If it is not remeber you have to adjust the windows registry before you enable it.
I have the Asus P6te motherboard, as far as I know it is Sata 2.
ah sata 2. then yes, thats normal.
edit: quick google search says p6t is sata 3. the red ports. i dont know about p6te though
If thats the socket 1366 x58 board that I think it is then it is sata3. Make sure the ssd is plugged into on of the upper red sata ports.
Then check the bios to see if the sata controller is set to AHCI, but dont turn it on yet if it is set to IDE or compatibility.
