The uptime is close to 99.9%.

The stability is quite good. Our system is in production and we have not had any problems with it. When a drive fails, we don't really have any disruption because we can easily rebuild the disk, even if it very large.

I did buy a new case with lots of fans as I was having a problem with a disc failing every couple of years. Until this last disc failure, it was probably up for over three years without a hitch. Stability, for the most part, is pretty good.

FreeNAS is highly stable, and the performance is okay. It continues to run year after year.

Extremely stable, provided that your hardware is rock solid (I am talking about the mainboard, SATA cables, etc. not the hard drives themselves

No issues encountered.

It is stable. We haven't been running into problems with it.

The solution has been very stable so far.
