Other World Computing reports that it has discovered a fix for an issue with SATA performance on Apple's latest 17-inch MacBook Pro models that has caused problems with solid state drive performance.
For over a month, we've been following reports from some MacBook Pro 2011 model users - almost exclusively those with 17" models, where issues with other brand 6Gb/s SSDs have been encountered. The main issue reported was that the drive simply wasn't being seen/working.
Investigation of the issue reveals that it appears to be related to the battery indicator cable and the SATA connection cable to the drive running next to each other at one point within the machine's chassis, resulting in interference that is degrading SATA performance. The cable configuration is unique to the 17-inch model and thus the issue has not been demonstrated in the smaller 13-inch and 15-inch MacBook Pros.
In order to address the issue, OWC is offering a cable shielding kit priced at $9.99. Users who purchase a new OWC-branded drive for installation in their machine can obtain the shielding kit for a discounted price of only $2.99.
