For what it's worth, 3Ware's latest PCI-E cards (9650 series) now support RAID 6. The updated twa driver that supports them hasn't yet been merged into FreeBSD (see kern/106488 which I filed 2 months ago) but you can download either the source or the binary for it from 3Ware that works just fine. The updated 3dm2 for it did make it into the Ports tree.
I noticed that when I was making my reply from earlier. At some point in time I may test out the newer (twa-based) cards. It seems that 3ware is actually interested in supporting those. They never managed to get the twe driver out of what they called "beta", so that's where my experience ended.
Interesting thing - When I installed FreeBSD on the new system (pre-6.2 version discs) it didn't see the new Areca card. I started to get worried but quickly found out that the driver had been updated shortly before 6.2 was released. Quick update and all was well. So the kernel driver *is* being updated.
Driver annoyances aside, my 9650SE is considerably faster than my 9500S (both have batteries, both have the drive's write cache off), especially on writes, and they are both much faster than my Adaptec 2410SA (which has no battery option and thus needed write caching disabled).
I haven't tested the current system in speeds, but it's noticeably faster than my other (1160 PCI-X) system. Possibly due to the fact that I was using WD4000YR drives in the first which do not support the updated speeds of SATA2. The current system does and the card detects it. The newer card also has an updated processor - Intel IOP341 instead of an IOP33x series processor which I would guess makes a big difference. At least according to synthetic benchmarks going around the net. :)
I've never tried Areca. I would probably like them, from the sound of things. I'm sticking with 3Ware for SATA systems for now though... but hey, personal preference and all. For my next SCSI/SAS system I may have to do some serious evaluation of what's new out there...
Regardless of what you choose, there are a few decent options for FreeBSD now. Shows that people out there are actually starting to care about FreeBSD for some of these controllers.
Unfortunately, I didn't have the same solid results with the mirroring (RAID1) support for onboard SATA (Supermicro X7DVL-E). I mirrored two SATA2 drives (OS) and tried pulling one drive. Placing it back in didn't automatically start a rebuild, but I could force it. Pulling it, restarting, and then removing the drive from the RAID1 array (via the BIOS) would then cause FreeBSD to panic at boot (or drive insertion) every time. I don't know if it was the fact that there was still metadata on the drive so the ataraid driver thought something differently, but it bothered me a little. I had to disable ATA RAID in the BIOS completely (and remove the ataraid device from the kernel) to get FreeBSD to boot or allow the drive back into the system at all. Since the motherboard RAID is just software RAID, I switched over to gmirror but kept AHCI on so I'd still have hotplug support. After that I wasn't able to kill the system.
