Hello! I suffer already half a year. There is LaCie USB3.0 ExpressCard/34 and MacBook Pro 17" Late 2011 (MD311). I can't force to work in any way the card under OS X with USB3.0 speed (W/R 35/39 MB/s max!!!)
On the same laptop under Windows 7 BootCamp with Renesas drivers, the card perfectly clings HDD and gives out the decent speed of copying.
 
There's your problem. Your Macbook has USB 2 ports, not USB 3. Apple only started using USB 3 in 2012

What a nonsense, he bought an express card with USB 3 ports and there are drivers provided by Lacie and I even provided the link.

You clearly didn't read nor understand do you.:eek:
 

If you click on The Apple Menu and then about this Mac, then click on More info System Profiler Opens, your Express card should be mentioned under PC or PCI cards, what does it say?

Edit: I think you do have a USB Cable do you, if not then that is the problem.

External container USB3.0 with hard disk. At other computers works normally, speed ok.

Very odd, the only thing what I right now can think of is NTFS USB 3 speed is not supported but HFS+ might be although that sound also implausible to me.

Edit: I recommend you to contact their customer service or support.

Edit Again: The only thing you might try is repairing permissions.

I updated my last post, essentially saying to try to repair permissions, might help.
There can be fault a hardware incompatibility? But then why in Windows speed corresponds to USB3.0? How to make Repair Permissions? Through Disk Utility?

Yes through Disk Utilities.
Hardware is Ok, permissions repair just sets the permissions to the correct ones if they are of, and it happens.

Open Disk Utilities, click on the Volume under the internal disk and click repair permissions, can take a while, if it repaired files you better do a restart.

You should use Fresco Logic based cards, like:

(Mac) OS X >= 10.8.2 supports Fresco Logic based cards without additional drivers.
