1. A method for securely storing and retrieving data, the method comprising:

  • generating, using an electronic computing system that includes processing circuitry, a plurality of shares by performing a cryptographic operation on a data set and distributing the data set in the plurality of shares such that the data set can be reconstructed using any subset of the shares that includes at least a minimum number less than all of shares;

    storing the plurality of shares at a plurality of storage devices;

    receiving, at the electronic computing system, request to retrieve the data set;

    identifying from the plurality of storage devices a set of fastest-responding storage devices necessary to retrieve the minimum number of shares, wherein the set of fastest-responding storage devices are identified based at least in part on the response time of the storage devices;

    retrieving from the set of fastest-responding storage devices, the minimum number of shares;

    reconstructing the data set using the minimum number of shares; and

    sending the data set responsive to the request.
