Under Serial-ATA Device Tree, System Profiler shows this for my April 2010 15" MacBook Pro/2.66GHz/Core i7/8Gb RAM/OS X 10.6.8 (Build 10K549):

Intel 5 Series Chipset:

Vendor: Intel
Product: 5 Series Chipset
Link Speed: 3 Gigabit
Negotiated Link Speed: 3 Gigabit
Description: AHCI Version 1.30 Supported

Is a 6Gb HDD compatible? (My external drive has failed, and I'm wondering whether I can replace my internal with a 6GB 7200 RPM drive [to use its 3GB 5400 RPM drive in my enclosure].)

Thanks.
