Fujitsu MHY2120BH Device Specifications, Specifications summary, Self-diagnosis, Write cache

Device Overview

(5) Self-diagnosis

The disk drive has a diagnostic function to check operation of the controller and disk drive. Executing a diagnostic function of the smart command invokes self-diagnosis.

(6) Write cache

When the disk drive receives a write command, the disk drive posts the command completion at completion of transferring data to the data buffer completion of writing to the disk media. This feature reduces the access time at writing.
