Data storage system durability using hardware failure risk indicators

A data storage system, comprising:

• a plurality of data storage elements;
• and
• at least one processor configured to determine a hardware failure risk indicator for each of the plurality of data storage elements, and to assign a quantity of replicas of a data object and a distribution of the replicas of the data object among the plurality of data storage devices based at least in part on the respective determined hardware failure risk indicators for each of the respective plurality of data storage elements.

A non-transitory computer-readable medium storing computer-executable code for improving data durability, the code executable by a processor to cause a device to:

• assign respective hardware failure risk indicators to each of a plurality of data storage elements in a data storage system;
• and
• store a plurality of replicas of a first data object among the plurality of data storage elements, with a quantity of the plurality of replicas and also a distribution of the plurality of replicas among the plurality of data storage elements being determined based at least in part on the respective hardware failure risk indicators assigned to each of the respective plurality of data storage elements in the data storage system.
