I have 10 data disks and a Movies share set to high-water. Now when I copy movies to the share they copy to say disk1 then the next time disk3 and so on. Now I understand why (the high-water setting) but how does that benefit?? All I see is having 20gb of data being copied onto a 250gb drive leaving 230gb and the next copy goes to a different disk, which then in turn when I want to watch a movie from the share it spins up a bunch of disks.

 

Can someone explain why this is a good idea??

 

I am not knocking anything, I just don't understand 

Do a search for highwater on the forum. Ive got at least 3 threads on this very problem.

 

But to summarise. It doesn't help when the array is parity protected. In fact it is a significant hindrance. Hopefully the siggested partial fixes will eb implemented in the next beta.

Thanks NAS...glad it was not just me.
