Indeed. But for Myth media storage, is it better to have single
drives and multiple storage directories ? If writing multiple streams
to a RAID array, then that involves all the drives and performance
isn't necessarily better than a single drive (all that seeking). I
believe Myth will try and spread recordings across multiple storage
directories - thus aiming to write a single stream on each drive.
And then there are those who suggest ZFS is a better option anyway ...
