Be sure to check for the latest firmware for the SSD and flash it before
even using it. Also check for any well known issues with the particular
SSD. And a decent backup strategy is never a bad thing ;-)
With that flaky ssd I had scripts to quickly rsync the partitions to
hdd-based storage so I could rather quickly switch back and boot from
there. That ssd worked and looked OK for weeks and then *ZIP* changed
its mind and its size to 0 bytes ... that wasn't too funny.
The ssd in my thinkpad is completely robust and problemfree.

This would be a new dell laptop (latitude E series). I do daily backup
of my user data now and will continue with the new laptop. I hope my
experiences match yours with the thinkpad.

seriously, intel had once some calculations that even with lots of daily
writes you could go on for years as long as you did not fill up the ssd
completely.

So you have these on a HDD? /var for large write count reasons and

mostly because 64 gb is not so much
But sparing the ssd a lot of writes is an additional bonus.
