I don't think there are a lot of companies who do care about FreeBSD7 
(or FreeBSD at all).
For many, it's rather a nuisance (from my perspective). They only 
support it, because a significant portion of their sales depends on it.
Can anybody make a statement about the status of the Areca driver?
Because that's the only other non-SCSI controller I know that is worth 
I think some of the higher-end MSI-controllers are also good. And of 
course, the HP P600 and P800 controllers - but to fully make use of 
those two, you need a special enclosure anyway....
