Abstract: Embodiments of distributed storage systems are disclosed herein. Certain embodiments maintain statistics associated with storage locations within the distributed storage system at servers within the distributed storage systems. The statistics maintained at each server may be particularized to that server with respect to each storage location. These statistics may be utilized to predict access costs associated with requests for data (e.g., read or write requests) within the distributed storage system. The predicted access costs are, in turn, used to select a storage location in servicing the data access requests increasing computer performance and efficiency at least by decreasing access involved with requests for such data.
