Attribute

Status Flags

Threshold

C0h

Power-Off Retract Count (Unsafe Shutdown Count)

The raw value of this attribute reports the cumulative

number of unsafe (unclean) shutdown events over the

life of the device. An unsafe shutdown occurs whenever

the device is powered off without STANDBY IMMEDIATE

being the last command.

0 (none)

C5h

Pending Sector Count

The raw value of this attribute reports the number of

current unrecoverable read errors that will be re-

allocated on next write.

0 (none)

C7h

CRC Error Count

The raw value of this attribute reports the total number

of encountered SATA interface cyclic redundancy

check errors.

0 (none)

E1h

Host Writes

The raw value of this attribute reports the total number

of sectors written by the host system. The raw value is

increased by 1 for every 65,536 sectors (32 MB) written

by the host.

0 (none)

E2h

Timed Workload Media Wear

The raw value of this attribute reports the wear seen by

the SSD (since reset of the workload timer, attribute

E4h), as a percentage of the maximum rated cycles.

0 (none)

E3h

Timed Workload Host Read/Write Ratio

The raw value of this attribute reports the percentage

of I/O operations that are read operations (since reset

of the workload timer, attribute E4h).

0 (none)

E4h

Timed Workload Timer

The raw value of this attribute reports the elapsed time

(number of minutes since starting this workload timer).

0 (none)

E8h

Available Reserved Space

This attribute reports the number of reserve blocks

remaining. The normalized value begins at 100 (64h),

which corresponds to 100 percent availability of the

reserved space. The threshold value for this attribute is

10 percent availability.

E9h

Media Wearout Indicator

This attribute reports the number of cycles the NAND

media has undergone. The normalized value declines

linearly from 100 to 1 as the average erase cycle count

increases from 0 to the maximum rated cycles.

Once the normalized value reaches 1, the number will

not decrease, although it is likely that significant

additional wear can be put on the device.

0 (none)

F1h

Total LBAs Written

The raw value of this attribute reports the total number

of sectors written by the host system. The raw value is

increased by 1 for every 65,536 sectors (32 MB) written

by the host.

0 (none)

F2h

Total LBAs Read

The raw value of this attribute reports the total number

of sectors read by the host system. The raw value is

increased by 1 for every 65,536 sectors (32 MB) read

by the host.

0 (none)
