Hi,
Supposing you have 3 non-overlapping recordings a day plus some events
which cause noflushd
to spin the disk up/down, let's max it to 10/day then -- which is quite a
lot I think.
Then with 50000 start/stop cycles it would be specified for about 13.5
years.
In 2015/2016 I will have a 15.8 TB holographic crystal in my box and then
noflushd will be turned off
anyway :-)
