What generation of ExpressCard is the T420? is it gen 2?

I have a ViDock on my current lebnovo laptop (W500) connected via ExpressCard.  the performance is limited due to the speeds of ExpressCard 1.0.  I will soon be getting a T420 and was wondering what generation of ExpressCard it is as I hope it is 2.0 to provide better performance.

That info is very good. I was wonder although the data rate for the 2.0 spec is not there. I was wondering if I will need it later on since USB 3.0 was ommitted from my T520 and that chipset doesn't support it. Hmmm

 

I wonder if the SATA 6GB interface is implement here or not internally. It mentions that eSATA is 3GB interface and with my i7  T520 system I/O is everything.

 

Its interesting also the Wireless LAN does not list the Intel 1x1 PCI Express half mini card supported it. I view that as important since this WiFi card has been a problems from day 1. WiFi connections on 11g are 48 -24Mbps and never 54 unless I am literally beside the router. It occasionally drops but reconnects quickly (I get the bleep when that happens).

 

I've kept the Bluetooth 3.0 off since it appears to slow down internet loading a lot regardless of connection speed. I've used it once officially to transfer files off my Palm Treo PDA and boy or boy did that take a long time.
