SSD lifespan

[Fateh]

Hello,

Proliant G10 DL 380.

I got three SSDs to run RAID 5:

The vendor informed me that it has lifespan of 4500 GB. Which means if my DB writes 50GB a day, then the SSDs will be dead within 100 days.

On the other side, the video below suggests that SSD are durable, we just need to keep 10% free.

Could pls clarify the lifetime matter.
