Hi Frank, there’s not much construction anyway. I used both sata connectors for 2 identical 320 GB Notebook Drives which I found in the workshop. The second Drive is indeed powered by the “Fan” connector. (Found out by risking an old HDD) I think, the “Fan” Label might be wrong.
I use the original Ubuntu image, regularly updated. No modules, no nothing just mdadmin creating a RAID1. I defined 3 mirrored Partitions: /var, /home and /Data. Thus, I can boot from the first SD-Card-Partition, mount / on the single 8GB Partition on the emmc-chip and then /var, /home and /Data from HDD. This gives me the following opportunities: the SD-Card is readonly (longer life ) The System as such is located on the relatively fast EMMC, and having /var and /home on HDD gives me a bit more space on emmc.
Too sad ich can’t append Pictures here, but if you like, you can take a look here:
