Write cache function

Page 109 highlights

10.10 Write cache function Write cache is a performance enhancement whereby the device reports the completion of the write command (Write Sectors, Write Multiple, and Write DMA) to the host as soon as the device has received all of the data into its buffer. The device assumes the responsibility for subsequently writing the data onto the disk. • While writing data after completed acknowledgment of a write command, soft reset or hard reset does not affect its operation. However power off terminates the writing operation immediately and unwritten data is lost. • The Soft reset, Standby (Immediate) command, and Flush Cache commands during the writing of the cached data are executed after the completion of writing to media. So the host system can confirm the completion of write cache operation by issuing a Soft reset, Standby (Immediate) command, or Flush Cache command to the device. before power off.

Write cache function
Write cache is a performance enhancement whereby the device reports the completion of the write command (Write
Sectors, Write Multiple, and Write DMA) to the host as soon as the device has received all of the data into its buffer.
The device assumes the responsibility for subsequently writing the data onto the disk.
While writing data after completed acknowledgment of a write command, soft reset or hard reset does not
affect its operation. However power off terminates the writing operation immediately and unwritten data is
lost.
The Soft reset, Standby (Immediate) command, and Flush Cache commands during the writing of the cached
data are executed after the completion of writing to media. So the host system can confirm the completion of
write cache operation by issuing a Soft reset, Standby (Immediate) command, or Flush Cache command to
the device. before power off.
