The way I try to look at this is:
1) How much more do the enterprise grade drives cost?
2) What are the benefits? (Faster performance, longer life, etc)
3) How much does it cost to deal with downtime, diagnose issues, and
replace malfunctioning hardware?
My personal take is that enterprise drives are usually worth it. There
may be consumer grade drives that may be worth considering in very
specific scenarios if they still have power loss protection and high
write durability. Even when I was in academia years ago with very
limited budgets, we got burned with consumer grade SSDs to the point
where we had to replace them all. You have to be very careful and know
exactly what you are buying.

Usually it doesn't, it only harms performance and probably SSD
lifetime
