    • 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.
    • 可以从第一数据单元计算完整性单元,并且可以请求第一存储设备来存储第一数据单元。 可以请求可以与第一存储设备分开的和/或不同类型的设备的第二存储设备将包括完整性单元的元数据存储在非易失性存储器中。 此外,响应于对第一数据单元的请求,可以从第一存储设备接收第二数据单元。 可以从第二存储装置接收完整性单元,并且可以分析第二数据单元和完整性单元,以确定第二数据单元是否与第一数据单元匹配。 或者,第一完整性单元可以存储在非易失性存储器块的元数据区域中,其中块还存储计算第一完整性单元的数据。

    • 可以从第一数据单元计算完整性单元,并且可以请求第一存储设备来存储第一数据单元。 可以请求第二存储设备,其可以与第一存储设备分离和/或不同类型的设备,以将包括完整性单元的元数据存储在非易失性存储器中。 此外,响应于对第一数据单元的请求,可以从第一存储设备接收第二数据单元。 可以从第二存储装置接收完整性单元,并且可以分析第二数据单元和完整性单元,以确定第二数据单元是否与第一数据单元匹配。 或者,第一完整性单元可以存储在非易失性存储器块的元数据区域中,其中块还存储计算第一完整性单元的数据。
