SATA II performance on ASROCK 939 dual sata2

[thepcgeek]

Have WD 200gig sata II drive on ASrock 939 dual mobo. mobo uses the Jmicron chip for sata II. I get 240mb/s using HDtach. Is this normal? Can i consider that Sata II?

thanks

Couple things.
1st: This is not HT.
2nd: http://www.anandtech.com/storage/showdoc.aspx?i=2450]SATA II article[/url]: SATA II does not imply faster transfer speed than SATA.

:-(
apparently anandtech doesn't like bbcode?
