> Anyone using these? Not yet, but I'm excited about USB 3.0. SATA600 will become more important down the road, though probably only for SSDs. Even today's best SAS 15,000rpm magnetic drives can only reach about 200MB/s (Seagate 15k.7), with 7.2k SATA drives closer to 150MB/s. However, SSDs are already at the limit of SATA300. In contrast, USB 2.0's 480mbit/s theoretical bandwidth (with actual performance closer to 300mbit/s) was a big limitation before it was even released, so USB 3.0's raw 4.8gbit/s throughput is a huge improvement over the previous version that can be felt almost immediately.

All current SLC and MLC Intel SSDs are SATA300 only, and even then only achieve a maximum speed of 250MB/s. In fact, I suspect that it could actually run slower with an add-in card vs. the Intel SATA ports built into the chipset.
