[Arm-netbook] iMX233-OLinuXino development started today

[Gordan Bobic]

Hard to tell without having tried it, but generally SATA port 
replicators work fine (e.g. Silicon Image SIL4726 1:5 multiplier). The 
only thing to watch out for is whether the host controller can handle 
FIS switching (and has to fall back to command based switching). If it 
can't, the performance will drop off as you add more drives. I have 
measured a combined throughput performance degradation of about from 
about 95MB/s with 1 disk attached down to about 64MB/s with 4 disks 
attached when the controller cannot support FIS based switching.

Whether that is actually relevant in most use-cases this SoC will find 
itself in is debatable.
