Sata III 6G

[Yoga]

Since the 2011 MBP supports SATA III, one would imagine the necessary modified kexts are available in both the 2011 MBP install disk (illegal) and the 10.6.7 MBP combo update (legal).

Anyone had a look into this yet? Is there any reason we can't get this working now?

Awesome - thanks. Will install and benchmark...

I installed it, however, I am getting the same speeds as I was before (check the first few pages of my guide). I was already getting SATA3 speeds whenever I had this as "Unknown ACHI controller". Seems cosmetic to me.

Same here, benchmarks are identical (both SATA II & III drives).

It did bug me seeing Unknown chipset, nice to have it tweaked. It appears to detect which drives are SATA II and III correctly. There must be another kext involved for actual functionality.

Just noticed this - what speeds do you get in XBench? Could you post a screenshot?

You notice my read speeds are over 300MB/sec. You ONLY see those speeds on a SATAIII enabled drive. If it was still SATA2, it would be around 275MB max.

Yes indeed, SATAII limit is 300MB/s, and devices rarely hit maximum.

I have a SATAIII HDD which bences 400MB/s read on Windows 7, and only 220 in OS X. If I recall your thread screenshot, you installed the JMicron SATA driver didn't you? That seems to be the only difference between our systems. Are you using that port, or the Intel?

I'm using the only two ports on my motherboard that are SATA3 for my SSD's (one for OSX boot, one for Win7 boot). They are intel I believe.
