I'm considering a case with low capacity (TB) requirements, but life expectancy and reliability is important, i.e. I can probably make do with 1 TB or less. There will be some r/w activity, but not close to the rated TBW of a standard consumer 2.5 in ssd. I can always add a higher capacity hdd for non-essential data (cameras feeds etc).
The environment is less than optimal, vibrations are expected, temperature cannot be guaranteed to stay well below 40 deg C, power outages likely to occur (although UPS for safe shutdown is included). Unless complete HW fail or requirements change, which would require changing entire server, the system is expected to last for 10 years. Maintenance is possible, but costly.
I'm thinking ssd > hdd for this case? Or will they die before hdds anyway?
Which raidz setup would be better for ssd? mirrored? raidz2?
