So I'm considering replacing my DSM 5.2 virtualised build with FreeNAS 10. I'm after a supported system that isn't a 'hack' to make it work and that also has bitrot protection etc. built in to it. My use cases will be general media storage as I use an alternative system for ESXi cluster. Xpenology using DSM 5.2 has served me well, especially SHR2 with mixed sized drives... but now I don't need to worry about that, but as the system does look after my family photos I'd rather not let corruption occur in them. Outside of Copy on Write and the checksumming using RaidZ(x), does FreeNAS have any benefits or disadvantages to Xpenology? Memory isn't issue and neither is vCPUs... i just want a reliable, speedy (WD red speeds e.g. 115MB/s+) storage system for general usage. Thoughts?
