<font class="Apple-style-span" face="arial, sans-serif"><span class="Apple-style-span" style="border-collapse: collapse;">With my current system I have found that my largest disk IO hit comes from trying to flag commercials while watching live TV rather than just recording multiple shows at once.</span></font><div>
<font class="Apple-style-span" face="arial, sans-serif"><span class="Apple-style-span" style="border-collapse: collapse;">Also with 1 SATA drive I have had no problems recording 3 HD shows (1 from HD-PVR and 2 from HDHR) but I start to run into problems once I try to watch one of the recordings while commercial flagging is going on.</span></font></div>
<div><font class="Apple-style-span" face="arial, sans-serif"><span class="Apple-style-span" style="border-collapse: collapse;">Separating frontend/backend would probably help me but I think turning off commercial flagging temporarily works well enough. Also having a separate drive for LiveTV only would help if the FE/BE are on the same machine.</span></font></div>

If you just have a 60-120 gb drive for Live TV I could see it helping if you if you want to record 3+ shows while watching LiveTV.<br clear="all">
