5.4.2 SMART Logs

The Intel SSD 320 Series implements the following Log Addresses: 00h, 02h, 03h, 06h,
and 07h.
The Intel SSD 320 Series implements host vendor specific logs (addresses 80h-9Fh) as
read and write scratchpads, where the default value is zero (0). Intel SSD 320 Series
does not write any specific values to these logs unless directed by the host through the
appropriate commands.
The Intel SSD 320 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 320 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.
Tab le 14 lists the Device Statistics supported by the Intel SSD 320 Series.
