I run Rockstor on my NAS which is an "old" Ryzen 3950x with 32GB RAM. It has 4 SATA SSD drives 120GB - for the system itself 2x 960GB 1x 480GB And it has 4 NVMe m.2 drives 1x 4TB 1x 250Gb 1x 750gb 1x 960GB They all run as a single btrfs drive mode with no redundancy. Been like that for almost a year now so far and all the drives we're previously used in other systems that I have before I put them in the nas. Absolutely zero issues. Love it. Every single time that I've tried using a rotating drive in an nas it just fails. Be it a WD red NAS drive or some random laptop HDD I have lying around. Don't listen to people that say ssds fail. The way prices are going right now I'm going to try to pick up more of the four terabyte nvme drives and replace the rest of the nvme drives in this nas one by one. If I could get every drive except for the small system drive to be a 4 TB drive that would rule. But there is one exception. I have had reliability issues on this machine using a external nvme dock that's over USB c. And it's only with this particular OS or maybe it's just with Linux because it's fine in Windows and it has to do with how the dock doesn't give a unique serial number to the drive and also sometimes it just provides a very flaky connection and I was having a little bit of problems with that and as soon as I removed it from the array all the problems went away.
