i'm about to buy an extra esata port expresscard, there are sata 2 and 3 versions, 3 is priced a little higher, but am i right in thinking that only the main bay and the ultrabay support sata 3 anyway?

ExpressCard - Wikipedia, the free encyclopedia
Since on the T420, the ExpressCard is fully ExpressCard 2.0 compatible (support 5.0 Gbits), so it is faster than SATAII (3 Gbps) and slightly slower than the SATAIII (6 Gbps).
t420 expresscard port - sata 2 or 3?
