As NAND Flash devices age with use, the capability of

the media to retain a programmed value begins to
deteriorate. This deterioration is affected by the
number of times a particular memory cell is
programmed and subsequently erased. When a
device is new, it has a powered off data retention
capability of up to several years. With use the
retention capability of the device is reduced.
Temperature also has an effect on how long a Flash
component can retain its programmed value with
power removed. At high temperature the retention
capabilities of the device are reduced. Data retention
is not an issue with power applied to the SSD. The
SSD drive contains firmware and hardware features
that can monitor and refresh memory cells when
power is applied.
 Endurance rating is how much host data you can
write to the drive at a specified workload and
operating and storage temperature for the specified
drive life. For more information on the specific
workload to achieve this level of endurance, see
JEDEC Specification JESD218. TBW is defined as
1x10^12 Bytes.
Limited Warranty with Media Usage provides

coverage for the warranty period or until the SSD
Percentage Used field in the SMART Health Log
reaches 100 whichever comes first.
