Discussion can sandy bridge cpus run gen 3 sata ssds at gen 3 speeds?

[jordanbuilds1]

im currently having a discusion with a friend with a (mobile) i7 2760qm, he thinks that just because he has a gen 3 sata ssd its going to run at gen 3 speeds, im telling him that its going to be limited to gen 2 speeds, whos right?

The likely chipsets are HM65 and QM67 and both support SATA III, so I see no reason that a SATA III drive wouldn't run at close to full speed. The motherboard manufacturer may have opted to not allow for SATA III speeds, but it would probably be cheaper to just implement it at that point.

SATA II would be around 200MB/s SATA III would top out around 550MB/s

You may be recalling that initial Sandy Bridge chipsets had a severe issue with the four SATA gen II ports (3Gbit SATA-300) where Intel expected 5-15% of them to fail within 3 years. There would be no reason for a mobile platform to use any of those ports as just the two SATA gen 3 (6Gbit SATA-600) ports should be sufficient for them, so mobile devices were not affected or recalled.

The SATA gen 3 ports run at SATA gen 3 speeds.
