Adaptec is proud of their "HostRAID" technology that has a spotty
record with Linux compatibility. The manufacturer's descriptions
have led people to mistakenly think they bought a hardware RAID
card when in fact the RAID functions are implemented in software.
This approach has been dubbed "fake RAID". It's not clear to me
that this is a win compared to using the kernel's software RAID
features.
http://www.brentnorris.net/blog/archives/158 tells the sorry tale
of a company whose products used to be a safe bet. The comments
tend to confirm the sad state of affairs.
