5.4 Device Statistics

In addition to the SMART attribute structure, statistics pertaining to the operation and health of the Intel® SSD 730

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 following table lists the Device Statistics supported by the Intel SSD 730 Series.

This statistic counts up from 0 rather than down from 100,

and may go beyond 100 for drives that exceed their

expected lifetime.

5.5 SMART Command Transport

With SMART Command Transport (SCT), a host can send commands and data to an SSD and receive status and

data from an SSD using standard write/read commands to manipulate two SMART Logs:

 Log Address E0h ("SCT Command/Status") — used to send commands and retrieve status

 Log Address E1h ("SCT Data Transfer") — used to transport data

5.6 Data Set Management Command Set

The Intel SSD 730 Series supports the Data Set Management command set Trim attribute, which consists of:
