5.4.2 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).
5.5 Device Statistics
In addition to the SMART attribute structure, statistics pertaining to the operation and health of the
Intel SSD 530 Series can be reported to the host on request through the Device Statistics log as
defined in the ATA specification.
The Device Statistics log is a read-only GPL/SMART log located at read log address 0x04 and is
accessible using READ LOG EXT, READ LOG DMA EXT or SMART READ LOG commands.
The table below lists the Device Statistics supported by the Intel SSD 530 Series.

This statistic counts up from 0 rather than down
from 100, and may go beyond 100 for drives that
exceed their expected lifetime.
