And I thought I found one in the Adaptec 1405 Integrated SAS/SATA
controller, because it's marketed as an inexpensive SAS/SATA non-RAID
addon-card. On top of that, they advertise it as having FreeBSD6 and
FreeBSD7-support and drivers. So I ordered it for my storage-box
(FreeNAS) with great expectations. Sadly, they don't have support nor
drivers for FreeBSD ("drivers will be released Q4 2009") at all, so I'm
thinking of leaving FreeNAS and trying some linux-flavor that does
support this card...
But Adaptec doesn't have a great track-record for FreeBSD-support, does it?
