[mythtv-users] Storage speed requirements for record/playback?

[Matt D. Robinson]

Hi, all.  I'm looking to externalize my storage from my front room
if at all possible to eliminate drive noise.  I think I can do
this with iSCSI, but the question of speed comes up.  What are the
typical drive speeds required for record (write), playback (read),
and a simultaneous read/write scenario with something recording
while something is being played back?

I can drive 60-80MB/s full duplex with iSCSI, about 40MB/s each way
for sequential operations, but is that sufficient?  What would be
normal for record/playback/both?

Externalizing the storage from the HTPC with iSCSI means I can
drive the data to another room on a gigabit NIC over a long distance
to another server in my garage without any noise.

Thanks in advance for any feedback people can provide,
