Is it safe to stream media from the array when i'm checking parity?

Yes, but it does slow down the parity check and performance doing whatever you are doing will be reduced. If you are watching movies you may experience glitches depending on your setup.

 

In general I suggest running parity checks during times you do not plan to use your array.

and what about during preclear? safe to play movies from it?

Yes... it is safe.

It is safe and you should not experience slowdowns either (unless you are running drives using a PCI controller).

 

I would not think twice about using the array during a preclear.

ok thx
