The recently-released MacBook Pro firmware that promises to enable 3.0Gbps SATA connectivity has ironically been causing problems in third-party drives. Apple released the upgrade earlier this week, after users of the new 13- and 15-inch MacBook Pro models reported that the notebooks were limited to 1.5Gbps SATA; this did not affect the speed of standard-fit hard-drives, but may have limited future performance should the user upgrade to a faster HDD or SSD. Now, some users with third-party drives already installed are reporting frequent pauses, usage spikes and data errors with the new firmware.
