I think I've been reasonably serious about my SWARM and despite issues elsewhere the onboard PATA interface is a part of the system I've never had any with. Yes, it's limited to PIO 3, but it's not a big deal, that's still 11MB/s (and one of the 4 generic data movers present in the SoC could be used as a DMA engine to offload the CPU if anyone bothered implementing that in the HBA driver). I used it for stuff like native GCC bootstraps, some regression testing. Maybe I'm just lucky, I've read people's horror stories. Besides I'm out of free PCI slots, I'd have to use an expansion box.
