|The SATA 150 designation indicates the burst speed of a SATA I drive. SATA I drives are no longer made. The current models are SATA II/ 300MBPS.|
You should be able to use MOST SATA II drives on your SATA I controllers. A few of the SATA II performance drives are designated as SATA II ONLY. Which means they will not work on your board.
You MAY need to set a jumper on the SATA II drive to force SATA I speeds.
As far as performance is concerned you won't notice any real world difference in the speeds. What may help is most new hard drives have a larger cache than older IDE drives had. That does increase overall performance.
You need to be concerned about the capacity limitations of your motherboard. If the BIOS is not 48 bit LBA compliant you won't be able to use a hard drive larger than 127GB.
What capacity is your present drive?
