Unlike hard drives, solid-state memory has a limited number of write cycles. SSD hardware tries to optimize usage of the entire drive so that wear is distributed evenly, and to automatically disable degraded areas, but the service life is limited if you are a power user.
Usually the lifetime of a SSD is measured in the amount of data that's written over the lifespan of the drive. With current drives, you can expect durability equal to several hundred times the total drive capacity. So, if you have a 1Tb SSD, it might support something like 300 Tb being written to it before no longer being usable.
If you do the math for a typical PC user, SSDs can theoretically last hundreds of years. So, it's not really an issue unless you are running a server. One of the SSD's powering the PF server failed after about 2 years, for example.
Although hard drives don't have this problem, they are susceptible to mechanical failure are therefore no more durable if you ask me. If you want durability the best way to go is backup and redundancy. If you are using SSDs for long-term storage, just be sure to power them on once in a while so that the data doesn't vanish.
