There is a rule of thumb that states 1GB RAM per 1TB of storage, but I don't know how much you should value that...

But look at it this way: single 8/16GB sticks don't cost much more than 16/8GB kits, so I'd probably go for either 1 16 or 1 8GB stick and expend when needed. Which of the two options you should pick should depend on the budged, if you buy dual 8core Xeons then go 16GB, but if you buy a pentium G 8GB should pretty much be it

That rule applies for ZFS, unRAID does not need that much. ZFS needs RAM to properly work.

 

To OP: It depends on how much additional applications (Docker) and virtual machines you will want to run there. For pure NAS purposes, 4GB could be enough.

Jap, I know, and I run a NAS with 4GB of DDR3 just fine, but I guess it is a rule of thumb, that also makes sense in terms of budged, if you're going to spend 400 bucks on storge alone, why not drop another 50, to get to the 16GB barrier, where you are pretty much set for the next X years
