Properties Description
or equal to 90 percent and that for write protect
progress is less than the threshold value, which is
90 percent.
Warranty Coverage Expired — The drive has
reached the TBW threshold and met the life
expectancy specification. The drive is functional as
the number of spare blocks available are still above
the threshold for entering the read-only mode.
But, the specified data retention period (amount of
time that data can be read from the drive after
TBW is reached) drops, if TBW specification is
exceeded and the warranty for the drive expires.
The warranty coverage for the drive expires if the
value for percent lifetime used is equal to 100
percent and that for write protect progress is less
than 100 percent.
Approaching Read Only — The drive is running out
of spare sectors and is reaching the read-only
mode. However, the health status of the drive is
good and data retention is unaffected. The drive is
stated to be approaching the read-only mode if
the value for percent lifetime used is less than 100
percent and that for write protect progress is
greater than or equal to 90 percent.
Read Only — The drive is in read-only mode. Users
must save open files, if any, to another device and
replace or remove the device. If this scenario
occurs within three years of the device installation,
this failure is covered under warranty. The drive is
in read-only mode if the value for percent lifetime
used is less than 100 percent and that for write
protect progress is equal to 90 percent.
Driver Version Displays the version of the driver that is installed
on the PCIe SSD sub-system.
NOTE: Storage Management displays Not
Applicable for sub system for which the driver
version cannot be obtained.
Remaining Rated Write Endurance
Displays information on the SSD renewal/
replacement based on the amount of write
workloads. This field indicates the total remaining
programs or erase-cycles available on the SSD,
based on the cumulative specification of the total
NAND (Negated AND or NOT AND) Flash chips in
the SSD.
NOTE: This option is applicable to Micron
PCIe SSDs, Non-Volatile Memory Express
(NVMe) PCIe SSDs, and SAS/SATA SSDs.
