I'm still waiting with the rest of everyone else. In my case, it's a T60p.
It's been more than a month since Lenovo posted on this topic and a simple update from the company would be the right thing to do for the customers. We do matter, right?

@aaricia have you checked several usb devices to verify this? I have actually no problems at USB with the latest Bios and my T61p. BUT as the topic says is that when i use a PC Card also called PCMCIA for ESATA the Speed is around 10 MB/s and thats really poor...

Thanks for the reply Lurker.
Yes, I have tried several USB devices (stick and external hard drive) that work well on other computers.
Cant get USB up to speed still stuck at about 15 MB/sec...

I can confirm that the X61 has a new BIOS that has corrected this problem.
I have done testing with both the T61 and X61 models, and the latest BIOS have a much higher PCMCIA transfer rate. Now the maximum performance should be around 50 MB/sec.
USB performance should not be an issue. 15 MB/sec is about normal for USB, but it depends on the device you are using.
The maximum performance from USB should be around 35 MB/sec, but it depends more on your device.
Here are some USB benchmarks that show a minimum speed of 26 MB/sec with a fast hard drive. You might have a slow hard drive.

That's kind of strange. It seams that for on some versions (revisions of the thinkpad's motherboard?) the updated BIOS works and on some, it doesn't.
As you can see here:
This is on my X61s. Looks capped at 13.3MB/s. Maybe it's the thing with the "S" subversion - but the updated BIOS didn't correct the problem on my side :-(
I'm waiting for Lenovo's fix or acknowlegment of the problem.
