Shouldn't be country specific. I'm linking to the plain page without any country sub-directory. The link is this: http://support.apple.com/kb/HT3561 You should be able to get to the same page simply by searching support for "HT3561"

BTW, Apple don't specify what version of SATA drives are in their machines. It conceivable they use both SATA and SATA II, but it's not something that makes any difference to a 2.5" HD anyway. But machines with SSD have definitely reported 3Gbit interfaces, so they must "support" that interface in those cases. At least with the SSDs they sell.

Anyway, when has a computer manufacturer ever claimed to support any hard drive that they don't themselves ship or include in a published compatibility list? I think if you ever found a drive that didn't live up to expectations or didn't work, you'd be left to take it up with the drive manufacturer in most cases. Even Nikon and Canon don't officially support any media besides the ones they officially publish support for (and test against).
