Abstract
An integrity unit can be calculated from a first data unit, and a first storage device can be requested to store the first data unit. A second storage device, which can be separate from and/or a different type of device from the first storage device, can be requested to store metadata, which includes the integrity unit, in nonvolatile memory. Also, a second data unit can be received from the first storage device in response to a request for the first data unit. The integrity unit can be received from the second storage device, and the second data unit and the integrity unit can be analyzed to determine whether the second data unit matches the first data unit. Alternatively, a first integrity unit can be stored in a metadata region of a nonvolatile memory block, where the block also stores the data from which the first integrity unit was calculated.
