The german magazine c't ( just tested the new USB3.0

fastest 3.5", 7.2k min^-1 SATA drive currently available.
Sustained reads (min/avg/max): 84 / 138 / 178 MByte/s
Sustained writes (min/avg/max): 50 / 101 / 177 MByte/s

Problem is, the disk has no fan and after 100 GB or so it gets so hot
(63°C) that write speeds go down to 50 MB/s as the disk does a "read
after write" when it gets so hot ...
