So your SSDs seems to last 4-6 years.

I'm currently typing on a box running on 13 years old HDs.
They've been used on a server (so always on) for maybe 5-6 years, then 
demoted to a desktop machine and they've been cycle-powered daily for at 
least other 6.
I even have older, still working, rust around.

When an HD gets to small/slow for its purpose, I replace it with a 
bigger shinier one, but I just move the old one to a less demanding use, 
backups/archive being the lower step in their life.

Seems not, then.
