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).
