Solid state drives don’t crash at all in the same way that spinning disk drives do.
A spinning drive can literally have one of its read/write heads crash into the ferrous surface, often destroying both. These drives have been around a long time, however, and a lot of safeguards are built into them to help avoid it. If the power goes out, or the drive senses free-fall it will park the heads in a safe place so no crashing.
However the semiconductor memory in a solid state drive can have its state changed only so many times and then it starts becoming unreliable. That number tends to be in the several thousands.
Early solid-state drives had trouble especially in places that were written/re-written frequently such as directory areas or a portion used as swap space.
Current SSDs have several features built-in to help avoid failures.
The semiconductor structures are fortified for longer write-cycle lifetime, more state change cycles.
There are several zones of spare memory that can be used when an active region wears out, commonly as much as 20% extra.
The SSD controllers also keep track of how many times each area has been used to load-level where the next write goes, and they can move data from an area that has been used a lot into a less-used area.
