This lesson presents a brief summary of this chapter.

We have discussed data protection in modern storage systems, focusing on checksum implementation and usage. Different checksums protect against different types of faults; as storage devices evolve, new failure modes will undoubtedly arise. Perhaps such change will force the research community and industry to revisit some of these basic approaches or invent entirely new approaches altogether. Time will tell. Or it won’t. Time is funny that way.
