I just realized the other day that I have never had an SSD die.
I just had one die today and it's a Tier 1+ - Intel Enterprise/Data Center Drive. Luckily it's in a RAID. Just a little over 3 years old. Whether you use Tier 1 or Tier 2, RAID if you need up-time. Always have backups. However, I will say the failure rate is way lower than hard drives even enterprise hard drives.
Disk on Controller 0, Port 2
Status: Failed
Model: INTEL DC S3510
Main advantage stems from power loss protection and higher write endurance. If you're the type of person that likes to push hardware more than 5 years, I would go for the better quality drive.
