Opinions on switching to QuTS hero?

Long story short my TS-251+ died awhile back, although I was able to revive it with the 100ohm resistor fix, and it is still running but I also went out and got a TBS-464 replacement and I have x4 4TB nvme chips installed.

When I first bought it QuTS hero was not available yet for that model although it was advertised as such so I just went ahead and loaded QTS. I haven’t really done much with it yet and I want to change the RAID config anyways since I have a better all around backup solution in place now and in RAID 6 I don’t get as much of the overall capacity as I would prefer. I think I want to go with RAID 5.

I’ve read to top level differences between the two OS but just not sure why I would choose one over the other.

Also it appears the forum has been completely revamped since last time I posted, lol. Can’t even find my old posts.

I would leave that TBS-464 on QTS, it has non expandable 8GB and ARC cache would be disabled on that low RAM if you switched to QuTS.

Thanks dolbyman! It is not always clear what nuances may be out there when making these decisions. I always like trying new things and it seemed like there might be some optimizations with SSDs on QuTS hero.

On another note what is the easiest way to refresh the drives and go with a different RAID option? Do I just delete the volume pool and reformat, etc?

If you would switch to QuTS, those drives would be formatted anyways, so nothing special you would need to do

Understood on that aspect but I don’t want to switch if there is no real value or if the NAS HW doesn’t benefit in any way because of RAM limitations like you mention.

Oh, hmm I would always do the easy way and clear all drives (I have a couple of cheapo USB to NVMe bridges that I can do a “clean” via diskpart.)

But you can also do a factory reset from the GUI (on the bottom of that page, below the reset button options)
