Intel® Solid-State Drive 320 Series
Note: 1. B7h and C7h attributes are available with firmware version 4Px10362 and later.
Tab le 13 defines the SMART Attribute status flags.
1.
C7h1
CRC Error Count
The total number of encountered SATA
interface cyclic redundancy check (CRC)
errors.
110010 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 (32MB) written by
the host.
110010 0 (none)
E2h
Timed Workload Media Wear
Measures the wear seen by the SSD (since
reset of the workload timer, attribute E4h),
as a percentage of the maximum rated
cycles.
110010 0 (none)
E3h
Timed Workload Host Read/Write Ratio
Shows the percentage of I/O operations
that are read operations (since reset of the
workload timer, attribute E4h).
110010 0 (none)
E4h Timed Workload Timer
Measures the elapsed time (number of
minutes since starting this workload timer). 110010 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.
110011 10
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.
110010 0 (none)
F1h Total LBAs Written
Counts sectors written by the host. 110010 0 (none)
F2h Tota l LBA s Rea d
Counts sectors read by the host. 110010 0 (none)
