What is the difference, and why does it matter?
The basic difference is the number of bits recorded in a single
cell, and that affects both the storage density and its
long term reliability.

More bits == more dense but less reliable.

To compensate for long term reliability, SSD manufacturers use
a variety of strategies involving staging data in RAM,
compressing it, and implementing other special storage
structures.

On a removable-media flash device, none of those strategies
are used.

Perhaps I misunderstood. I thought you were referring to usb flash drives.
Do you mean these little chip gizmos that go into digital cameras?

(Hope I am not being a nuisance.)
