Besttechie Posted June 22, 2009 Report Share Posted June 22, 2009 Last week, there was a discovery that Apple apparently downgraded the SATA hard drive interface to 1.5 Gbps in the latest 13" and 15" MacBook Pros when compared to previous-generation MacBook Pros running at 3.0 Gbps. While users were unlikely to max out the 1.5 Gbps transfer rate unless they had installed an aftermarket fast solid state drive (SSD), there were still concerns about Apple's decision to scale back the interface speed (as well as a number of rumors as to why they did it).Apple today addressed the issue with the release of MacBook Pro EFI Firmware Update 1.7, which allows the new MacBook Pros to utilize the full 3.0 Gbps interface.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.More info here...B Quote Link to post Share on other sites
isteve Posted June 23, 2009 Report Share Posted June 23, 2009 I kind of though it would be a firmware update seeing that they use the same chip set. Quote Link to post Share on other sites
