Just recently I have lost power three times (never used to happen). I am about to buy a UPS to deal with the recent issues. What I have noticed is the lincstation seems to have a hard time rebooting/booting. I have to long press to reboot or even at times unplug the unit if long press is not working. I have to do this several to many times to get the unit to boot properly. It typically is stuck on flashing all lights. This happened after every power outage. Oddly enough, its also happened with just regular shutdown/startup scenarios. I added extra SSD's to redo my drive setup, converting from array to ZFS pools. In this process I had to reboot several times and several of those reboots experienced the same startup issues. I am not sure if there is something wrong with the internal flash or not, but its a pain to get this device to boot sometimes. However when it does finally boot, it works great. I am attaching my diags if anyone is interested. tower-diagnostics-20250816-1647.zip

Interesting, maybe buying one more m2 for now, starting ZFS with 3 devices, would improve the expansion in the future. Would ZFS allow me to expand the RAIDZ pool with both 3.5 inch SSDs and the M2 slots? I assume they would all have to be 2TB?

Are there people running the standard array with parity disk on all flash without issue? Is it a real concern even with modern flash drives? Some conflicting information around the drives need to rely on their own TRIM processes since Unraid would have trim disabled. I have also read that modern, high quality, flash drives would not be impacted. However nothing definitive. I have read both the lincstation, and unraid documentation and its still not clear to me what the pros/cons are for ZFS versus unraid array with parity on all flash setup.

Just for clarity, you recommend this based on extending the lifespan of the flash storage? Because of the trim issue? If I spend the time to rebuild, I also loose flexibility with expansion in the the future. When I initially scoped out the hardware, I assumed I could expand to 10GB in the future as needed by adding two additional M2 drives and two SSD's. I was under the impression I could add one of the four at a time and just slowly expand. With ZFS, I would have a max of 6TB and have to add them in pairs I believe? That and they would be separate pools of storage where I have to juggle which shares are assigned to which pools? The ZFS example is based on assuming I wouldn't have the ability to back everything up and rebuild it when adding new disks.

New to unraid and NAS in general. I have a lincstation N1 with two 2TB Samsung Evo Plus m2 drives. I setup one as parity and got the array up and running. It runs a few docker containers but mainly plex. My concern is the array, I came across some articles suggesting that I should use ZFS pools instead because its all flash storage. I have an opportunity now to rebuild it before the storage exceeds some other SSDs I have lying around to back everything up. What is the current thought on this? Should I rebuild it with ZFS pools instead? Unraid version 7.1.2.
