Question

Modern ssds use a technique called "____" to spread write operations around the storage medium, thus evening out the impact of destructive writes and extending the storage device's useful life.

Answer 1

The question above has multiple choices as below;

a.      Wear aggregation.

b.      Wear mitigation.

c.      Wear prevention

d.      Wear leveling

The answer is d) Wear leveling.

This technique by some SSD controllers to increase the memory’s lifetime is called wear leveling. The mechanism for this principle is simple: distribute the entries for all the blocks evenly so that they will wear out evenly. Flash controller typically manages wear leveling and uses a wear leveling algorithm to control which physical block to use.
