The 3Ware RAID cards I have vastly outstrip the motherboard built in Intel RAID
implementations for a RAID 5 setup. (I don't consider RAID 1 to be economically
sensible for most uses.) A four disk RAID 5 SSD configuration can be
breathtaking fast, too.

I would point out that I'm not sure I've ever really seen the benefit of "Real
Raid" except for the vendor making more money. The only place I've used it is in
iSCSI boxes that run everything in firmware.
On all computers / servers, I've always used MDADM on Linux and ZFS on FreeNAS.
Both have been excellent for my intended use, though FreeNAS is only at home
for ~3 concurrent users, so take that whole thing with a grain of salt. Neither
has lost data due to power outages or drive failures.

Me too. LSI gobbled them up.
Well, consolidation is often a good thing.
You can still buy best performing 3Ware 9750 (2011 model!) from LSI, they are
selling them for those who are fine with 6 Gbps speeds. Don't think they'll be
upgrading it to 12Gbps (not that many people are interested in real
RAID-supporting cards at such speeds, these are mostly for connecting external
storages...)
