I started with a 3-desk RAID5 full of 2TB disks. This setup seemed to
choke around 3 recordings, 2 commercial flagging, and 1 playback (it
would probably stumble without the playback, too).
I had a spare 1.5TB disk, so I added it to the storage group. I
haven't had any IO issues since.
I now have three storage groups:
Almost everything I record is set to Default, but occasionally I will
set something to Important if I want it to survive a drive crash.
Sometimes I will move files from /mnt/wdgreen15/recordings to
/raid/recordings if I decide they are important to me. When Myth fails
to find the file at the specified path, it tries the other storage
group path(s) and succeeds. This way I have some redundancy for
important recordings. I would not care if I lost the independent 1.5TB
disk (or even the whole array)--it's just TV.
