With SSD storage, what what your thoughts on redundant storage devices (e.g RAID1), is it a waste, a nice to have or a must?
what are your experiences and thoughts on this ?
Appreciate your opinion, as I will probably move from HDD to SSD.

SSD's are cheap nowadays. They're also much more reliable than HDD's. That said, when they fail it's usually catastrophic failure with total data loss.
If your data that's important to you, I would still use redundant storage. Especially since the cost is minimal.
The cheaper SSDs can be very failure-prone though. I actually use second-hand spinning disks in my server and I have a whole bunch of spares waiting in the wings. I am still backed up though.
Had a Kingston SATA SSD that I had used for my plex server data (not media), and it ended up dying on me. First drive I had actively fail on me and cause data loss.
It was redundant after that.
That's interesting because Kingston's usually have a reputation that proceeds them. I currently have some cheap Chinese knock-off SSD that I've put through hell and it keeps plugging away.
Yeah the one I had after it died, I cracked it open.
Was a super cheap PCB that had like 1 or 2 nand packages.
The overall construction of it just felt.. cheap, even though at the time it was a higher rated model.
That's the entire problem with those knock-offs: almost no quality control. So it can be very hit or miss. Bottom line is that if you care about your data, you'll back it up! 😉
All I gotta say is my media pool has 3 replicas.
2 at home, 1 in Colo.
I never plan on losing data anymore.
Currently my Plex data is split between my old instance at home which has my watch history, and will probably still use when watching 4k.
The new server is on a 5x 12tb z2 pool, lol.
In total I'm probably around 160-170tb raw storage total.
