This has been posted before, and the main reason nobody got very
excited is that:

a) it only uses the PCI bus to provide power to the device, not for I/O
b) It is limited to SATA bandwidth
c) The benchmarks did not prove it to be noticeably faster than a
good single SATA drive

A few of us were really excited at first too, until seeing the
benchmarks..
