[mythtv-users] S-ATA versus plain old parallel

There are issues around S-ATA and Linux with older kernels, but any
recent(ish) distribution should be fine. I installed MythTV on an 865G based
Intel board using the Fedora Core atRPMs as per Jarod's guide and have had
no problems running a S-ATA drive as the only drive in the system.

As for performance, I get around 50 MBytes/sec sustained transfer rate
(using hdparm) from the drive which *way* more than Myth is ever going to
need short of multiple (3 or 4) HDTV streams - and that isn't available yet
in New Zealand anyway.

I'd definitely recommend the Intel 865G chipset for a Myth box (but then
again, the only 2 boards I've setup Myth on are that one and my laptop - a
Dell Inspiron 8100), the only thing it's missing is a TV-out (and some
boards include this too - mine didn't so I'm using the PVR350 TV-out). It
has been rock-solid though, no hangs, lockups or other funny hardware
related bugs which it seems like some other chipsets can suffer from. The
onboard audio, USB, video and LAN are all natively supported too.

The other advantage S-ATA *may* give you is given that most HTPC boxes are
small form factor (or small cased), the cabling for parallel IDE can
restrict airflow while the smaller S-ATA cables are less likely to - YMMV.
