A computer includes a data transform algorithm, a data dispersal algorithm, and a network port. The data transform algorithm performs a data transformation on a data block to produce a transformed data block. The data dispersal algorithm performs a data dispersal function on the transformed data block to produce a plurality of data slices, wherein each of the plurality of data slices includes less than all data contained in the transformed data block. The network port is operable to transmit a plurality of write commands to a plurality of slice servers, wherein each of the plurality of write commands includes a corresponding one of the plurality of data slices. The network port is further operable to receive verification of storage of at least some of the plurality of data slices from at least some of the plurality of slice servers.
