There is a big difference between SD cards, USB sticks and real SSDs
too. And there is another big difference between consumer SSD and
Enterprise gear. Here is some real world data. Drive has been in
pretty much constant use in production at a public library running the
online catalog and in house cataloging / automation / etc. since 2011.

So yeah I trust SSDs now in production workloads. It is in a RAID1
though so trust but verify is still the watchword. There are six of
these drives in the three servers making up our Evergreen install, all
bought at the same time and all still going strong. Unless something
unusual happens they are more likely to be taken out of service for
being too small than becoming unreliable.
