In my own rig I have an old IDE disk for the root filesystem, database etc.

Then I have a WD WD10EACS for recordings, which is an older green series
drive.

My record is 7 recordings - 3 DVB-S and 4 DVB-T, off two tuners, whilst
watching a previously recorded show. Note that none of these were HD
recordings.

On the test rig I'm still using some older Seagate 250GB HDs. and I've run
over 8 recordings, some in HD, across 3 tuners without any recording or
playback issues.
