Reliability specifications

The following reliability specifications assume correct host and drive operational interface, including all interface timings, power
supply voltages, environmental requirements and drive mounting constraints.

Read Error Rates
Unrecovered Data
Miscorrected Data
Interface error rate:
Mean Time Between Failure (MTBF):
Annualized Failure Rate (AFR):
Preventive maintenance:
Typical Data Retention with Power removed
(at 40C up to 90% of write endurance)

Endurance Rating:
1. Error rate specified with automatic retries and data correction with ECC enabled and all flaws reallocated.
2. 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 reten-
tion 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 re-
duced. 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.
3. Endurance rating is the expected amount of host data that can be written by product when subjected to a specified workload at a specified op-
erating and storage temperature over the specified product life. For the specific workload to achieve this level of endurance, please reference
JEDEC Specification JESD218. TBW is defined as 1x10
4. Limited Warranty with Media Usage provides coverage for the warranty period or until the SSD Percentage Used Endurance Indicator, as defined
in Section 5.2.6, reaches 100 whichever comes first.
