MacBook Pro Firmware Update Fixes SATA Bottleneck

EFI Firmware Update 1.7 was released by Apple yesterday which addresses issues using SATA 3.0Gbps specification solid state and standard hard drives with the June 2009 MacBook Pro. The firmware update increases the allowed transfer rate giving users full speed data transfer on the 3.0Gbps interface.

MacBook Pro EFI Firmware Update 1.7 addresses an issue using drives based on the SATA 3Gbps specification with the MacBook Pro introduced in June 2009.  This update allows drives to use transfer rates greater than 1.5Gbps, however Apple has not qualified or offered these drives for Mac portable computers, and their use remains unsupported.  All previous and current Apple portables with a SATA drive interface include a SATA 1.5Gbps hard drive.

The update requires Mac OS X 1.0.5.7 to install. Full support documentation is available on Apples website with instructions on how to apply the update.
