[1] A similar approach for data integrity was added in 2016 to the NVMe 1.2.1 specification.

[2] Packet-based storage transport protocols have CRC protection on command and data payloads.

But the reliability of the software, its ability to detect errors, and its ability to correctly report or apply corrective actions to a failure have a significant bearing on the overall storage system availability.

The data exchange usually takes place between the host CPU and storage disk.

[1] This extended sector is defined for Small Computer System Interface (SCSI) devices, which is in turn used in many enterprise storage technologies, such as Fibre Channel.
