Done a bit of reading on this this morning cos I was experiencing some slow transfer rates on a 10.5.6/7 build over the weekend.
What appears to be going on here is the drive installations in the lower end 13" and 15" models are reporting in the About This Mac->Info that the drives are SATA1 (effectively).
Many many people are getting this - many many are also buying the cheaper models of their mbp, removing the original drives and installing SSD - getting SATA1 still.
However what the majority aren't checking, but those who're used to upgrading macs are, is the bus via the Disk Uitility which reports all drives including the opticals as being SATA2.
Looking deeper into this, and consequently thinking I've solved my personal issue; earlier I saw reports from both original install and *other* installs of 10.5.7/10.6 of laptop battery use increasing by (from the examples) 10%, 33%, 42% - people were up in arms about how the heck are they making my hardware run longer.
Answer seems to me that the performances of certain things are throttled accordingly. Whether these things can be adjusted ala performance options, I'm not sure, but I will be looking into it for some builds.
In conclusion to the 10,000+ post threads I've seen about tho - the SATA hardware is certainly not SATA1, tho it does appear, for varying reasons, certain models are running/throttling to those speeds - but staying on longer.
I envisage an *update* that will make them all run at 3g, but not stay on quite as long. Question of what u want I guess.
