A few recent threads have inspired me to consider using an ARM device for PVR purposes.

Although the latest RPi seems like a good candidate, I think I am going to go with a Rock64 - please feel free to suggest anything better out there.

I have a Digbit R1 on my network and the idea is to connect a hard drive directly to the Rock64 (rather than recording directly to my NAS).

I have a few initial questions:

1. How much RAM should I go for?  Is tempting just to go for the maximum 4GB as it is not that much more expensive.
2. What sort of hard drive can I connect to the device, before I start needing additional power?
3. What is the eMMc module? Should I use this in preference to an SD card?
4. How well does the Rock64 perform generally?  Is it as stable as a RPi?

Thanks
