#External graphics card for macbook pro usb 3.0 drivers
eSATA does not work for my HDD sadly, but this hardware might work now that some drivers are available from Apple. I know the limitations of Express card bandwidth, and that it cannot give full USB 3.0 speeds for PCI based express card but a USB 3.0 support means a definitely higher speed for my 1TB seagate GoFlex Freeagent HDD. The Express card Adapter would provide USB 2.0 speeds in OSX as there was no USB 3.0 support, but since now we have USB 3.0 support does the adapter work and give better speeds than before. Since OSX Mountain Lion brings in native USB3.0 support, did any one try the seagate USB 3.0 upgrade cable package with express card adapter?

This question is specifically about ExpressCard/34 USB 3. I currently have several Firewire 800 drives.

Please don't answer with suggestions about Firewire. Is there any card that doesn't require external power for USB 3.0 speeds? (Lacie don't mention this on their website as far as I can see). My biggest blocking point is the need for an external power supply.

I did a quick search and found a few drawbacks of the ExpressCard/34 USB 3 solution. I was wondering if it is worth my while getting an ExpressCard/34 USB 3 card for my 17" Macbook Pro, to tide me over until some reasonably priced Thunderbolt drives come out. There is a proliferation of portable and cheap portable USB 3 drives nowadays and nothing of the sort for Thunderbolt.
