As I (very) slowly grow using ZFS, I'm facing a situation that may be not ideal, I bet:
I started using a one partition pool on an HD populated with many HFS partitions and all is quite fine.
Recently, I had the idea to experiment using all the wasted space in those HFS partitions and gathered them in a second ZFS pool.
My second scattered ZFS pool is mounting little more slowly but I believe it's only because of its scatteredness...
All is still doing fine, but I wonder if the best practice wouldn't have been to create ONE ZFS pool and then create TWO DATASETS, instead?
Performance wise, would it be a better choice or it doesn't matter at all?
