Zusammenfassung:	Programmable disk drives are configured within a peer-to-peer redundant array of independent disks (RAID) that lacks a RAID controller. A spare programmable disk drive not part of the RAID can monitor a given drive of the RAID. If the monitored drive fails, the spare drive can replace the failed drive within the RAID such that it becomes part of the RAID, and reconstruct the data on the programmable disk drive that has failed by communicating with the other drives of the RAID. For each data block to be reconstructed, each such other drive may receive just one piece of data and sends just one piece of data. Further, the spare drive may receive just one piece of data for each data block to be reconstructed, which is the data block as reconstructed from one of the other drives of the RAID.
