Bad Block Scanning: Checks the flash memory for damaged sectors that might cause data loss. Speed Testing: Measures the actual read and write performance of the device to see if it meets manufacturer specs. Aging & Stress Tests: Evaluates the long-term stability and reliability of the storage product. Data Integrity: Can perform basic scans without destroying existing data, though deep tests for fake capacity often require a full write/read cycle. Pros Niche Expertise: Specifically designed to catch capacity fraud, unlike general benchmarking tools. Ease of Use: Features a simple, automated interface where users select a drive and click "Start". Detailed Reporting: Generates diagnostic reports to help users document evidence for refunds or disputes. Cons Aging Interface: The tool's UI can feel dated compared to modern alternatives.
