SSD Write Endurance 25nm Vs 34nm

This is the second time I’ve seen compressibility referred to as data randomness. Anyone know the issues related to why randomness of data is linked to compressibility?

All compression relies on finding some sort of pattern in the data, usually various kinds of repetition. Random data, by definition, has no pattern. Therefore, truly random data cannot be compressed.

Also, data that has already been highly compressed will no longer have patterns that can be exploited for further compression. That is what they mean by high entropy.
