Thinkpads Forum

Dear all.

Would love to run SL on my thinkpad x220 i5 quadcore with usb 3 port.
Need to know if anyone has everything working, USB 3 is a must.
Have seen that some people have usb 3 working but is it with true usb 3 speed?
As I understand only the sd card reader doesnt seem to work on some forums but an external card reader on the usb port should work, right?

I have a little experience but not to much, would be real grateful to anyone that can send me a manual or a disk copy for me to install. have a licensed copy of SL so am not breaking ´the law´
I just want to make my x220 a dual bootable workstation with windows 7 and SL.

Am an Artist living in Amsterdam and would be willing to send you some beautiful photography, (A print) as a gesture of my appreciation.

Thank you so much for any help, I feel this will become the computer of my dreams. A stable workhorse for me to work on with Final cut pro 7 and some Logic stuff.

Only the Core i7 motherboards in the X220 have the USB3.0 port. There are also no Quad core CPUs in the X220 (there are dual cores with hyper-threading - showing 4 logical cores). So please double check your sources.

It is possible to add USB3.0 support via an ExpressCard adapter.

Thanks for the news.

So does the express card provide true usb 3 speeds?
I am a video editor and on a macbook usb 3 meets more then my needs, will the speed of usb 3 on a thinkpad i5 with an adapter be in the same league?

Thanks for your time.

Yes, the ExpressCard adapters provide true USB3 speeds. Some of them are a bit flaky, though, in terms of reliability. Most specifically, the AKE 54mm dual-port ones, with Renesas uPD720202 chip, have power-management-related issues and require workaround to function properly in an X220 (but with these workarounds - their performance is superb).

Wow that is GREAT news amigo!
thanks for the help!
So what card is the best do you think, and if there is a work around, what is is it?

I have my eye on this second hand x220 i5 to make my ideal hackintosh computerrr.
Right?

Bless you

You can read my findings and summary in the following thread:

Specifically, the uPD720202 (54mm 2-port adapter with power plug) is one to be wary about. You can read about some of its problem and solutions here:

While the workarounds worked for me, it is a bit annoying to have to resort to them. Unfortunate, that is, since the card works great once you disable L0s. However for your X220 the ASMedia ASM1042-based adapter (which I also mention there) may be a good solution.

Finally, you can get USB3.0 and eSATA in one package, by using an adapter like this:

I have one, it is also based on ASM1042, so I would expect no strange issues. It performs well, but seems to drain quite a lot of power, even when idle, which will affect your battery life. I haven't performed accurate measurements, but plan to at some point.

Amazing reply man...

I very much appreciate you sharing your findings with me.

Regards!
