Above data are quoted from www.sata-io.org. The performance of G-
S350SUAB 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 connection. SATA is the better choice for storage device.
