I'm pretty sure I'll be buying DP soon. Will either use duplication for protection, or SnapRAID.
If I go with the former, and choose to use the plugin OrderedFilePlacement to disable balancing* and not make my HDDs spin all at once, then am I correct to assume that I will also need to think better about which HDDs I write to first.
Consider the following scenarios: (I know it's an extreme one in terms of HDD-size difference)
I currently have 1 x 8TB HDD and 2 x 2TB HDDs.
This will basically mean that if I want file-duplication with balancing off, I'll have to make sure that I fill the 2TB HDD first, before I start writing to the 8TB HDD? This is because, if I write to the 8TB first, and then this drive fails, its contents are too big for the 2 x 2TB HDDs to hold even with file duplication on. (12/2 = 6 TB, which is > 2 x TB HDDs).
Will I have to worry about stuff like that if I turn off balancing? I don't want to spin 2-3 HDDs just to play a movie file.
Note: I'm new to the concept of pooling and even newer to that of RAID so your patience is appreciated!

* That's what it does, right?
