Verified health — September 27, 2026
- SMART overall health: PASSED
- Extended self-test: Completed without error
- Media/data-integrity errors: 0
- Critical warnings: 0
- Available spare: 100%
- Rated endurance used: 15%
- Power-on hours: 8,006

For completeness, historical counters report 74 unsafe shutdowns and 96 cumulative error-information-log entries. The currently retrieved error log reports no errors. The cumulative error-information count is separate from media/data-integrity errors; the causes of the historical entries cannot be determined from the retained log.
Sanitization and preparation
Previous data was erased using the SSD controller's NVMe Sanitize Block Erase function. Successful completion was independently verified through the controller status log. Sampled blank-data reads across the drive also passed before reformatting.
The drive was then initialized as GPT and quick-formatted NTFS. A read/write check passed. Formatted capacity is approximately 238GiB, normal for a drive marketed as 256GB.
This is a used drive, not new or manufacturer-refurbished. The endurance figure is the drive's estimate, not a guarantee of remaining lifespan. Test results reflect its condition at the time of testing and cannot guarantee future reliability.
