please explain me the difference. and for the price of 32gb 30mbps card i can get 16gb 45mbps card in sandisk. so which is preferable for my T2i?
Either will do - they're the same, same capacity, same 30 Mb/s speed. The 'difference' is that the first one is an older card that has been discontinued (you can see that on the B&H website), but Adorama still has stock. It was 'rebadged' from Extreme to Ultra because Sandisk is now selling 45 Mb/s 'Extreme' cards and thus raised the Ultra line to the 30 Mb/s speed.

30 Mb/s is fine - the T2i will not use the extra speed, the only difference would be the 45 Mb/s card would transfer data to your computer faster (assuming your card reader supports the faster speed).
