Write Sector(s) (30h)
This command will write from 1 to 256 sectors as specified in the Sector Count Register. A sector
count of 0 (zero) will request 256 sectors. The transfer begins at the sector specified in the Sector
Number Register.
Write Sector(s) Ext (34h)
This command is mandatory for devices that implement the 48-bit Address feature set. The command
will write 1 to 65,536 logical sectors as specified in the Sector Count Register. A sector count value
of 0 will request 65,536 logical sectors.
SMART Support
Most SMART (Self-Monitoring, Analysis and Reporting Technology) commands are not relevant to
solid state drives. Therefore, there is no data to provide to a host SMART command. Zeus drives do
not abort these SMART host commands; the Zeus drives will report a “GOOD” status to all of these
commands.
Identify Device Information
The Identify Device command enables the host to receive parameter information from the SSD.
When the Identify Device command executes, the SSD sets the BSY bit, prepares to transfer the 256
words of SSD identification data to the host, sets the DRQ bit, clears the BSY bit, and then generates
an interrupt. The host can then transfer the data by reading the Data register. All reserved bits or
words are all zero. Table 9 contains typical Identify Device Information for the Zeus SSD.
