Seagate Barracuda 7200.11 ST31000340AS 1TB Hard Drive @ Viper Lair
 

The biggest change from the 7200.10 to the 7200.11 is the increase in platter size. We mentioned there will be a few capacities offered, but we can sum it up by saying that there will be 3; 500GB, 750GB and 1TB. If you're shopping for the 1TB version, another change from the previous model is the doubling of cache from 16MB to 32MB. The 500GB and 750GB will only ship with 16MB. As the name implies, the Barracuda spins its drives at 7200rpm, allowing for a sustained transfer rate of 105MB per second.
