Above data are quoted from www.sata-io.org. The performance of PHR-
100SU in your application might be higher or lower depending upon the hard
drive used, SATA and USB host and computer hardware. In our test, we
have seen over 60MB/s sequential read and write speed in SATA connec-
tion. SATA is the better choice for storage device.
