<p class="MsoNormal">Season’s Greetings TC-LUG’ers,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I run a DIY network of security cameras that work in two
parts.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">FTP (or server pull)</p>
<p class="MsoNormal">A number of cameras send jpeg images to server several times
a minute.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">FFMPEG<br>
Once a day, read last 24hrs of jpegs and write out the mp4 video.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Calculating the mp4 files takes most of the time, preventing
higher frames-rates, increasing sever load (impacting other uses) and delaying
availability of the final video.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">QUESTION</p>
<p class="MsoNormal">Since this is disk-intensive, I trust performance would improve
if Jpegs were written-to and read-from solid-state drive (SSD) as opposed to
traditional spinning mechanical-platter hard disk (HD).<span style> </span>I plan to continue writing the final MP4 to
HD.<span style> </span>Looking at RAID for faster reads serving
the final product.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I understand SSD are faster, quieter, more reliable, and
uses less power than HD (compelling arguments) but have a limited number of
read-write cycles before failure and are prone to fail on power outages.</p>

<p class="MsoNormal"> </p>
<p class="MsoNormal">If I run 5GB per day through a 120GB SSD what’s the expected
MTBF?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Otherwise, more ram and a faster cpu should help.<span style> </span>Any system design, hardware, or architecture
tips?</p>
