SSD Intel ICH10 AHCI SATA Link Speed at 3 Gigabit!

Mac Pro 2012

Installed SSD which is 6 Gigabit, but running at 3 Gigabit !

It says Negotiated Link Speed : 3 Gigabit

Please check attached screenshot, what am I missing?

New Firmware or Driver?

Please check attached 2 images, one showing 6 Gigabit Speed and other 3 Gigabit Speed, what’s the difference between these two devices in Mac Pro (5,1) 2010 model? One is Generic AHCI Controller (6 Gigabit) and the other is Intel ICH10 AHCI Controller (3 Gigabits) !!!

Nothing wrong here!

The systems SATA port is only SATA II (3.0 Gb/s) so putting in a SATA III (6.0 Gb/s) SSD won’t alter the systems I/O data path speed higher than what it is able to support.

Think of it this way… The escalator you are standing on is only going so fast, you can’t make it go faster.

Be aware not all SSD’s are able to negotiate (or work) at the slower I/O speed. Review your spec sheet for the given drive. If it doesn’t state its compatible, its a fixed speed drive!

Many drives today are dropping dual speed support Samsung SSD’s are one of the few that will work across all three SATA I/O speeds.

Still makes sense!

Your Mac Pro has more than one SATA I/O interface the Intel (built-in) and an add-on board (generic).

So the systems built-in SATA ports are only SATA II as you can see here: Mac Pro "Twelve Core" 2.93 (Server 2010) as an example.

The PCI bus your system offers allows you to plug in additional I/O boards in this case a generic SATA board which in that case offers SATA III ports!

This one says I can hook up two SSD drives to it for $100!

OWC Accelsior S

This one is for a single SSD selling at $48

So if I go with a

Sonnet Technologies

Tempo™ SSD

6Gb/s SATA PCIe 2.5" SSD Host Adapter and put my 2.5" SATA III drive on it, instead of having it in drive bay #1, I'm going to double my drives access speed?

I no longer have to be concerned if it is backward compatible?

Will I really see that much of a difference?

@mayer - The ability of the spinning disk of HDD will be the limit of how much data throughput you'll see. So a slow 5400 RPM drive won't likely push more than 3 Gb/s sustained. A faster 7200 RPM drive will push about 4 Gb/s.

Now the kicker a high performance SSD could push better than 5 Gb/s! The true limit of the SATA link is about 5.5 Gb/s (550 Mb/s). So that would be a good direction!

Now we still have the limits of the system, as not all of the PCI slots offer the full suite of lanes. So you will need to make sure you've got the board in the optimum slot.

@danj I just found this card that also has a 500 GB 6G drive bundled with the card for $108. I put a 860 EVO in drive bay #1 and got a dramatic speed increase, so this should really help my speed. Think I'll order it now, they also are having closeouts on lots of little stuff. addendum: Just ordered the bundled 500GB SSD with Accelsior PCI card for $108. I think this will be great little low cost upgrade for my MacPro.
