While a single SSD certainly is less power hungry than RAID5, it's
comparing apples to pears :-). But I got your point.

I wouldn't expect 10 years. I think that's a very long time for any
computer system (my home server is in its 7th... but I did replace disks
during that time). But if you were to build a dedicated LMS server using
eg. piCorePlayer, it would be easy enough to backup settings and
re-build a system within minutes if needed.

Just use it. I've read tests where they tried to simulate years of
"average use" by continuously writing TBs after TBs to SSDs. This was
late '17, and the title even mentioned "cheap SSD". And the result was
basically "don't worry about wearing out SSD any more". Some of them
took Petabytes of data written, before they gave up. But all of them
would write 600+ TB. That's a lot of data.
