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.

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 (32MB) written by

the host.

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 (32MB) read by

the host.

5.4.2 SMART Logs

The Intel SSD 525 Series implements the following Log Addresses: 00h, 02h, 03h, 06h, and 07h.

The Intel SSD 525 Series implements host vendor specific logs (addresses 80h-9Fh) as read and write

scratchpads, where the default value is zero (0). Intel SSD 525 Series does not write any specific values

to these logs unless directed by the host through the appropriate commands.

The Intel SSD 525 Series also implements a device vendor specific log at address A9h as a read-only log

area with a default value of zero (0).
