Against Harm's advice I put a partition on my raid 5. Can I merge these partitions safely within the windows environment (I know I'll need to do some file shuffling).
I also want to add a drive or two to the array (on an areca 1228i). Are there any dangers in doing this? Will the partition be a problem? (I ideally need to add the drives to get the space to do the file shuffling).
Finally, the array (currently 5 2tb ultrastars in raid 5) has never been fast. Any resources for optimising performance of areca cards - eg should I turn on AV Streams?
