This article is to help customers of both Solidigm™ (formerly Intel®) SSDs determine the health of their SSDs using a subset of important SMART attributes.
|Some SMART attributes may be product and vendor specific|
|Important Attributes||Attribute Name||Look-at Value||Threshold||Acceptable Condition|
|B8h||End-to-end error detection count||Normalized||90||91-100|
|E8h / AA (Duplicate attribute)||Available reserved space||Normalized||10||11-100|
|E9h||Media wearout indicator||Normalized||1||2-100|
|AFh||Power loss protection failure||Normalized||Fail=below 10||Shows huge number|
|05h||Reallocated sector count||Raw||1000||0-999 (0=best)|
The example below shows a good SSD. The look-at values per important attribute are highlight in yellow, which are all in a best-case state.
NVMe* SSD Example
These attributes can be analyzed in the example below. Some of the most important ones are highlighted in yellow. The Critical Warnings indicator is actually the most important one, as it captures all other important indicators. Unsafe Shutdowns should make sense for the SSD users, or there could be an issue with the OS driver (not sending safe shutdown signals).
Temperature indicators indicate if cooling is sufficient.
Percentage Used indicates media wear, and a value between 1 and 99 is acceptable, whereas 100 is not.
Fewer Media Errors indicate better SSD health. If any of the attributes mentioned here cross acceptable threshold limits, they result in Critical Warnings.
If you see any Critical Warnings, contact Solidigm™ Customer Support:
Solidigm™ (formerly Intel®) SSDs support SMART attributes listed in the product specification and implementation is aligned with https://nvmexpress.org/ standards.
