We did not use a different solution.

We used Proxmox before. Later, we switched to FreeNAS for better storage capacity.

We also use TrueNAS, which is exactly the same product but it is commercially supported and it has technical support included.

Prior to this, I also worked with a similar solution from NetApp. I prefer FreeNAS over NetApp.

The only other solution that I used, wasn't for the same. I do have a Western Digital network hard drive. I basically just use it to put on videos that I want to watch on TV. This solution didn't really replace that, however, this I use more reliably. I find it's very stable.

I have used WD network drives, but they are no where near as robust in the event of failure

Dell EqualLogic, and 3PAR. I like the 3PAR, but it is very expensive. Instead, I just spent money for fast SSD drives, installed FreeNAS, and you have a better solution then 3PAR.

We used Synology. We switched to FreeNAS because we just liked it a little more because of its flexibility.
