The 2220 and 2240 are _FRAID_.  No hardware.

Now these aren't the first software/host-based, 4-16 channel PCI-X SATA
RAID solutions to ever be introduced.  Broadcom has its RAIDCore series
as well.  But _unlike_ the Broadcom products, which actually have some
good software features (even for Linux), HighPoint seems to skimp on
software design.  They are rather simplistic in design and support
(e.g., no multiple card support).

Tom's Hardware didn't do any performance benchmarks, and what they did
was very minimal.  But they did do some queuing and other load testing.
The RocketRAID 2220 they tried _tanked_ compared to even the RAIDCore.

If you really want to save money, consider the Broadcom RAIDCore instead
of the HighPoint RocketRAID series.  Or get a real hardware card for a
few bucks more.

P.S.  In case you haven't heard, SATA-II is more "marketing" like USB
2.0.  You can't actually get 3GHz (300GBps) _unless_ it is SATA-IO.
Just like you can't get 480Mbps (60MBps) out of USB 2.0 unless it is a
EHCI controller.
