Abstract: An opportunistic storage service, or system, identifies currently unused storage capacity on a plurality of physical storage components of computing devices dispersed throughout a provider network. In some embodiments, the currently unused storage capacity is provisioned as primary storage, but is not currently being used to store primary storage data. The opportunistic storage service advertises at least a portion of the currently unused storage capacity as opportunistic storage capacity and provisions the opportunistic storage capacity subject to revocation if additional storage capacity of the physical storage components is needed to store primary storage data to fulfill a primary storage commitment.

Abstract: The following description is directed to managing a nonvolatile medium. The nonvolatile medium can be organized as a plurality of storage units. In one example, a method can include measuring read latencies for the individual storage units of the nonvolatile medium. A probability distribution of future read latencies for the nonvolatile medium can be estimated based on the measured read latencies for the individual storage units of the nonvolatile medium. Information can be moved from a particular storage unit of the nonvolatile medium to a different storage unit of the nonvolatile medium based on the estimated probability distribution of future read latencies for the nonvolatile medium.

Abstract: An adaptive read algorithm for accessing information stored on a nonvolatile medium. The nonvolatile medium can be organized as a plurality of storage units. A method of servicing a read request to the nonvolatile medium can include recording a history of read-retries for read requests to individual storage units of the nonvolatile medium. The method can include adapting a read algorithm for a read request to a particular storage unit based on the history of the read-retries for the read requests to the individual storage units of the nonvolatile medium.
