SMART Logs

The Intel SSD 530 Series implements the following Log Addresses: 00h, 02h, 03h, 06h, and 07h.
The Intel SSD 530 Series implements host vendor specific logs (addresses 80h-9Fh) as read and write
scratchpads, where the default value is zero (0). Intel SSD 530 Series does not write any specific
values to these logs unless directed by the host through the appropriate commands.
The Intel SSD 530 Series also implements a device vendor specific log at address A9h as a read-only
log area with a default value of zero (0).
