I recently installed OpenBSD on a Lenovo X1 Carbon with a solid state

My question is whether OpenBSD addresses the special characteristics
of solid state drives, especially those having to do with longevity
and reliability. I can't find anything written on this. Linux has
certain means for addressing this issue, such as fstrim as well as
various kernel options. Is there anything I have missed with OpenBSD
on this subject?

Any modern drive will have write levelling. Check the rated number
of writes for the drive. Run iostat for a week or two to determine
average writes/time interval. Compare that against 10% of rated
writes. When you get there, replace the drive.
500 TB is a good number for write endurance.
Completely writing a 1TB drive every day gives you 50 days.
Writing 100GB a day gives you 500 days...
Do you write 20 DVDs a day? That's your answer.
