The other day I told you that Apple a released new updates for MacBooks and Mac Minis, but then we were only talking about the implementation of support for the new LED Cinema Display and about solving some problems with Thunderbolt technology. Now I announce that Apple activated in the new drivers support for SATA 6 Gbps for MacBooks and this gives users the opportunity to transfer files through Thunderbolt with speeds that reach 6 Gbps, but the effective transfer speed depends on the storage unit in each Mac.
Apple doesn't promote the fact that the 2011 MacBook Pros and Airs support SATA 6Gbps because it isn't officially supported. I bet that it's because Apple can't get sufficient quantities of SATA 6Gbps SSD modules. Apple ships its current MacBooks with SATA 3Gbps SSDs and doesn't want to promote its SATA 6Gbps support until it can ship every unit with a 6Gbps SSD from the factory. What's the point of promoting SATA 6G when shipping SATA 3G drives?
Of course, only certain SSDs in the new MacBook Pro/Air are capable of reaching transfer speeds of 6 Gbps and for now the company does not promote the implemented innovations. In practice, you will not reach such high transfer speeds very soon, but theoretically they are possible, now you just have to be lucky enough to receive a MacBook Pro/Air with an SSD that is capable of reaching them. Probably in the future Apple will change SSD suppliers and offer users storage units capable of reaching transfer speeds of 6 Gbps via Thunderbolt or internally, but for now this is far from reality.
