Which SATA Ports are 3.0?

[1405]

On a Dell Optiplex 9010, there are 4 SATA ports; Black, Blue, White, White. Are the Black and Blues both SATA III? The White SATA II?

I found a reference to the older Optoplex 790, and it seems to suggest that. But I'm not sure if the Optiplex 9010 is the same.

Can't rely on that. Different motherboards, but maybe.

Do you know which form factor your 9010 is? They have different boards depending on the size.

Thanks for the quick reply. Yes, it is a mini tower like this one: http://
I guess I should have stated that.

From what I am reading I suspect you may be correct. The Q77 (Intel) Chipset mentions that only two channels support SATA III, however, usually one channel can support two drives. (The chipset supports up to 6 SATA devices, that Dell only broke out 4 might be cost savings)

The Dell service manuals for your model don't specify if the ports are different only that SATA 1, 2, and 3 speeds are supported.

That seems to make sense. I think I'll go with that. Wonder why they didn't just make the SATA 3 the same color? Maybe so the assembly folks can quickly tell which ports to wire the HDD/DVD to so all the builds come out the same?
