Apple to day releases MacBook Pro EFI Firmware Update 1.7 to address the SATA transfer speed issue. As previoulsy reported by many, the new generation of 13-inch and 15-inch Unibody MacBook Pros support 1.5Gbps SATA interface instead of 3Gbps as present in the previous Unibody 13-inch MacBook and 15-inch MacBook Pro. (Mac Rumors article)
According to Apple:
About MacBook Pro EFI Firmware Update 1.7 | 3.35MB
MacBook Pro EFI Firmware Update 1.7 addresses an issue reported by a small number of customers using drives based on the SATA 3Gbps specification with the June 2009 MacBook Pro. While this update allows drives to use transfer rates greater than 1.5Gbps, Apple has not qualified or offered these drives for Mac notebooks and their use is unsupported.

What does this mean?
Are the new 13-inch and 15-inch MacBook Pro natively supporting 3.0Gbps SATA interface?
It seems that the MacBook Pros are capable, but Apple does not officially support it.
Generally I avoid OS upgrade but this time I am giving it a try in a production machine.
Upgrading from Mac OS X Leopard to Mac OS X Snow Leopard Developer Preview on my MacBook Pro.
My colleague tested the upgrade on a MacBook Core Duo and it went smoothly.
I’ll see if the upgrade went smoothly on my MacBook Pro Core Duo.
P.S. I ordered another 320GB 7200RPM SATA hard drive for the MacBook Pro. It is still much cheaper than the 500GB 7200RPM notebook hard drive.
General requirement
- Mac computer with an Intel processor
- 1GB memory
