Max IO speed Sata2, despite system wide Sata 3 capable ?

[spyrule]

I've got the following :

FreeNAS 8.04
AMD A8 3870K BE
Asus F1A75-Pro w/6 SATA 3 connection (using the A75 built-in controller)
1 x Bytecc 2 x SATA 3 controller (with 1 IDE port)
8GB DDR3 1600
ZFS RaidZ2
6 x 1TB 7200rpm Sata3 HDD
1 x 30GB AData SSD (Sata 3) as cache

Why is it then, that when I set my hard drives speed when configuring the drives, the max I get is 3.0 Gbps, when it should be 6 ?

Here's a screenshot of what I'm referring to :




Thanks in advance,

Hi spyrule,

The pic is a bit small to really be useful, but my guess is that the chipset is "to new" for FreeBSD 8.2 & it simply doesn't know it can do SATA III speeds.

For grins you could try booting a FreeBSD 9.0 boot-only install disk & see what it reports the port speed at during bootup.

for some odd reason when I upload this photo it's shrinking it in size.
