Abstract
A technique for protecting stored information from read disturbance includes receiving a first write request to a solid-state device (SSD) in a storage pool that employs an erasure code. The first write request has an associated identifier and associated data. In response to receiving the first write request, the first write request is assigned to two or more SSD blocks of the SSD device based on the identifier. Pages of the associated data are then written to the assigned SSD blocks, such that each SSD block holds data associated with only a single identifier.
