iMac EFI Update 1.6 Adds 6 Gb/s SATA Capabilities

Other World Computing reports that the iMac EFI Update 1.6 released yesterday for Apple's new iMacs brings an unadvertised improvement in SATA performance for the internal hard drive bays.

While iMac EFI Update 1.6 is described as including "fixes that improve performance and stability for Thunderbolt," it would also seem that an unadvertised benefit is that it also unlocks the full 6Gb/s, SATA 3.0 capabilities of two of the internal drive bays.

Unfortunately, the optical bay remains at 3Gb/s.

The report notes that Apple also released an EFI update for the current MacBook Pros yesterday, but it is unclear whether that update attempts to address SATA performance issues found in the 17-inch models
