We bought our initial 2 TrueNAS servers from IX Systems (SuperMicro) back in 2011, have been upgrading over the years and they have been very reliable servers. Currently each server has 63 drives (4TB HGST NL-SAS) with 1 hot spare, configured as RAIDZ. Right now there is 200TB of usable storage, we initially started with 29TB and have been expanding as needed when it hits about 79%, I buy 18 drives roughly every 6-8 months, 9 drives per server and expand the pool. To say that we never had issues is lying, we did have some major issues when upgrading from versions, but this was early on, now it is a rock solid storage system. Although there is less than 300 active users connecting to the primary server, there is a lot of very important pre & post production high dev videos. Reboot with 63 drives is around 10 minutes or less. Resilvering could take 24-48 hours, depending on load, depending on how much data the failed drive contained. Performance has been great, reliability has been great, support has been great. Sadly IX Systems can no longer provide support after the end of this year, they've extended support beyond the expected lifetime of the hardware.
