Are you seriously suggesting a RAID setup where one half is the SATA-connected drive inside the laptop and the other is an external USB-connected drive? Sounds like a recipe for a world of pain for all the times that the external drive gets disconnected (not to mention the performance impact of having one half going over the slow USB2 connection, defeating the benefits of the internal SSD). For the BananaPi, the suggestion is marginally less problematic but still: a non-trivial constraint with significant immediate downsides. RAID is basically an insurance. Taking an insurance makes a lot of sense when it's important to spread the cost of the impact of an "event", but in my case the cost of such an event would be fairly low anyway (not to mention that RAID doesn't prevent me from losing work when the OS or my editor crashes, or when I make a mistake).
