Bad news, sports fans. It looks like Apple has downgraded the speed of the SATA interface in the newest revision of the MacBook Pro. While the previous MacBook Pros had a 3.0 Gbit SATA interface, benchmarks show that the current MacBook Pro only clocks in at 1.5 Gbit.
This is really only an issue if you plan(ned) on using a solid state drive. Traditional hard disk drives won’t even come close to maxing out a 1.5 Gbit interface, so there’s no need to worry in the slightest if you’re using a regular HDD.
It’s a different story if you’re using an SSD, as your top speed is effectively halved. Check out these benchmarks. The first pic shows a MacBook with a 3.0 Gbit SATA interface, while the second shows a new MacBook Pro with the slower 1.5 Gbit SATA interface.
No one knows what the heck is going on. Is Apple cutting costs? Is this an artificial limitation? Where will David Villa play next year? Question marks all around.
I’d like a side of lame to go with me McBogus Deluxe.
Do you want fries with that?
My guess is that Apple wants to save some money testing older hard drives and eventual support costs.
I believe there was a small number of older hard disks that only supported 1.5Gb/s SATA and could not negotiate the proper speed when connected on a 3.0 Gb/s SATA II bus.
Just in case Apple is listening: if you are going to enable this on the latest MacBook Pro, could you also release an EFI update for MacBook Pro 17″ (early 2008) as well? I know that the hardware is capable and it is a shame to see my 256GB Samsung SSD limited to 1.5Gb/s…
