[mythtv-users] Config suggestions for powerful MythTV Backend

I got it free from a client who had upgraded their servers recently
and doesn't run out of warranty equipment and had no need for it, so
giddy up for me :). Except the power usage and noise which I am little
concerned about, I guess I'll go plant some more trees in the yard.

That certainly sounds like the best option now that I understand the
storage group concept.

I do have a 2TB USB3 disk and PCI-E card in my current (to be
replaced) server used for backing up about 900Gb of data and hadn't
even thought about using the 1TB disk separately, I'm so used to
making sure the systems I set up are running RAID I guess...

LVM or mhddfs (had never heard of that before) would be good here.

I certainly will!
