SEAGATE 1200 SSD PRODUCT MANUAL, REV. A 15
5.0 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
1
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 retention capability of up to several years. With use the retention capa-
bility 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.
3. Endurance rating is the expected amount of host data that can be written by product when subjected to a specified work-
load at a specified operating and storage temperature. For the specific workload to achieve this level of endurance,
please reference JEDEC Specification JESD218. TBW is defined as 1x10
12
Bytes.
4. Limited Warranty with Media Usage provides coverage for the warranty period or until the SSD Percentage Used
Endurance Indicator, as defined in Section 5.2.7, reaches 100 whichever comes first.
