Hello everybody, from this first time poster and FreeBSD newbie!

I have a Corsair Force 3 SSD attached to an Areca 1880ix-12 that I
don't know how to configure to use SATA3.

The controller reports 'SATA600+NCQ' as operating mode, but dmesg shows:
da3 at arcmsr0 bus 0 scbus0 target 2 lun 0
da3: <Corsair Force 3 SSD R001> Fixed Direct Access SCSI-5 device
da3: 166.666MB/s transfers (83.333MHz DT, offset 32, 16bit)
da3: Command Queueing enabled
da3: 228936MB (468862128 512 byte sectors: 255H 63S/T 29185C)

bonnie++ confirms that max speed, which would be the equivalent of SATA1

I checked /usr/src/sys/dev/arcmsr and it contains not only references
to LSI2108, the chip used in this card, but also this:
**       07/15/2010              Ching Huang                      Added support ARC1880

I tried searching the lists and online for more information, but wasn't able to find anything. So my question is - how does one go about making this drive work at native speed? Or is SATA3 somehow not yet supported for this card?

I'm running FreeBSD 8.2-STABLE #0: Tue Jul 19 22:38:32 EEST 2011
