[mythtv-users] Filesystem of choice for recording drive?

I am using zfs with each disk being its own pool and snapraid for
redundancy. I have 6 data disks and 2 external drives that I use for
parity. The externals spin down when not in use. I sync 1 or 2 times
per week.

I consider that a bad choice. This drive is designed to limit the
error recovery to a very short period (even shorter than a NAS drive)
for usage in a video valence appliance where a few glitches in the
data stream is okay but its bad to stop recording for more than a few
ms.
