I'm not sure I'd agree if honest, although Brian and others may have a lot
more experience with HD set ups that I do.
I currently run a combined FE/BE *SD* setup, using 3 tuners and a single 1TB
WD Green drive (like you are planning) partitioned 3 times - 50gb ext3/4
(not sure without checking) for the OS, 8gb for swap (2xRAM), and ~908GB as
XFS for the recordings.
Right now (Christmas) the machine is under a lot of load. As an example,
the other night -
- all 3 tuners were active and recording SD
- mythcommsflagging was running (it's set to low cpu, so ~75fps)
- the missus was watching a recorded SD stream
- I was watching an SD stream from a remote frontend
That's 6 operations running simultaneously, one the one drive, no issues.
No jerky playback, no nothing.
IMO, I like the single drive setup. It allows a bigger choice of cases;
less chance of failure (running on the idea that 2 drives = double the
failure rate); less heat; and less power usage if you are planning to run
the machine 24x7 as I do.
Though, if none of the above are of interest to you, and if your usage will
be similar to the above but with HD streams (higher bandwidth/IO), I would
consider splitting. I'd also concede with Ron's point that two drives offer
Hope that helps,
