But to use something like the quattro docking station, either you have to use a USB connection (rather undesirable, especially since all those ARM thingies seem to be limited to USB-2.0 so far), or you have to use a SATA connection where the controller supports "port multiplier".

Both types support sata multiplier.

I lost you: both types of what? Both the i.MX6 and the A10/A20 SoCs?

You lost me twice. There Are two CuBox modules now: 1st CuBox/CuBox Pro. Which Has the Marvell Armada. http://www.solid-run.com/mw/index.php?title=CuBox_hardware_specification 2nd CuBox-I. Which comes in the four flavors of i-MX. http://imx.solid-run.com/wiki/index.php?title=CuBox-i_Hardware

Unfortunately they don't have a Allwinner A10/A20 version. There HW design is quite good and sw hacker frendly. Eg. built-in USB->UART chip.

...

Just read that the original CuBox does it better. The Marvell armada one. That is. It seems that the Inc doesn't support asynchronous transfer.

Are you saying that the Armada chip only supports the "command based switching" (so only one drive can be active at a time), whereas the i.MX6 (used in CuBox) supports "FIS–based switching" (commands can be sent to drives regardless if other drives still haven't finished processing previous commands)?

Just the opposite: 1st: Marvell Armada -> FIS Based switching 2nd: i-MX -> Command based switching http://www.solid-run.com/phpbb/viewtopic.php?p=8001&sid=c661b1aaed86bc1a... (posted by Rabeeh; The company's founder/CTO)
