3Gb/s is the sata bus maximum speed, not the drive real throughput.
See
http://www.tomshardware.com/reviews/wd6000hlhx-velociraptor-600gb,2600-5.html,
you'll see the maximum real througput for the velociraptor 600GB is 157
MB (~ 1,2 Gb/s), which is rarely obtained anyway in real life
(concurrent reading, access time, ... see
http://www.tomshardware.com/reviews/wd6000hlhx-velociraptor-600gb,2600-7.html).
So I bet your 200/300Mb/s are just corresponding to your disk
throughput (We actually have the same on our server at work with a
RAID 10 with 4 x 1TB WD caviar drives).
Kind regards,
Bruno
