Sexy as fuck. I want a 4U full of these.
One thing:
The chip also has a SATA 2.0 controller capable of supporting up to five 3Gb/sec ports; older 1.5Gb/sec SATA devices are compatible with this controller, but newer 6Gb/sec peripherals are not.
This is misleading; SATA 3 devices are all backwards compatible and will run fine on SATA 2 - they just won't run at SATA 3 speeds.
