There is quite a difference between common USB flash drives and SSDs. SSDs
are supposed to replace a HDD while USB drives are not designed for it.
One difference is the type of wear leveling, also documented here

There are exceptions of course, for example there some "industrial grade"
devices, but the commonly used ones can not be compared.
