Asus supplied the test drive for today’s benchmarks. A modified Vantec enclosure holds Seagate’s 7200.12 500GB drive and ASMedia’s new ASM1051 SATA-to-USB 3.0 adapter.

We have reservations concerning the use of such a mainstream drive to test an interface that is supposed to support 5.0 Gb/s transfers, yet even the USB 3.0 interface adapter is bandwidth-limited by its SATA 3.0 Gb/s backend. We hope faster devices will show up next year.

The NEC D720200F1 PCIe-to-USB 3.0 controller is common to both motherboards, shown below on the P7P55D-E Premium.
