"but having HDDs on 24/7 or even just when your using your PC wears them out incredibly quick. "
It doesn't, really, it's the actual writes and reads over time which causes wear, and powering-up and down, vice simply spinning up but doing almost nothing...
I've seen a few WD Blue drives still working fine with 26,500 hours on them, the equivalent of 3 years of 24/7 operation, or 9 years of 8 hours per day use...and as WD Blues are not really known for being bastions of durability, seeing them still work with even 26000+ hours impressed me.
In 'tests to destruction' a few years back involving hundreds of TB written, the Samsungs seem to last the longest. Conversely, Intel seems to have adopted an attitude where once you used 'X' amount of writes, the drive simply stops working, regardless of actual failure, a rather assinine feature of their software and firmware...but I'm not sure that still applies to their newer SSDs...
