A method for securely storing and retrieving data comprises: 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, a 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. -I LC) CD L~,E |
