RAID at all for me, actually. I've seen it crumble down to a grinding
halt several times (using software raid, mdadm, that is). While it was
designed so that a disk could fail without the service being
interrupted, in my experience a disk failing will still make the system
unusable. Either because the kernel goes haywire trying to adress the
non-working device or mdadm making decisions causing the entire set to
go offline.

Especially mdadm setups where you combine RAID-0 and RAID-1 sets to
achieve RAID-10 tend to break when there's problems.

Still, recovery is easier as the set can rebuild or data can be
retrieved from just one disk from a set...
