Samsung Magician is a free proprietary storage management utility created by Samsung. It is specifically designed to monitor, maintain, and optimize Samsung solid-state drives (SSDs). It serves as a centralized health and performance dashboard for internal NVMe and SATA drives, as well as portable external SSDs.
The official software can be downloaded via the Samsung Semiconductor Global Portal. Key Features
Firmware Updates: Installs crucial updates directly from Samsung to resolve drive stability bugs or security vulnerabilities.
Health and Lifespan Tracking: Displays real-time metrics including drive temperature, total bytes written (TBW), and overall S.M.A.R.T. health status.
Performance Benchmarking: Measures sequential and random read/write speeds, allowing you to compare metrics against historical tests.
Diagnostic Scanning: Runs short or full integrity scans to flag bad blocks and troubleshoot potential disk errors.
Over-Provisioning Management: Allocates a custom block of unallocated space (typically 10%) to optimize background drive garbage collection and extend hardware longevity.
Data Security & Management: Provides data sanitation tools like Secure Erase to completely wipe information back to factory conditions, or PSID Revert to reset hardware-encrypted drives.
Performance Modes: Offers specific optimization toggles such as “Full Power Mode” for high-end NVMe drives to keep performance at a peak. Platform Availability
