U

Device Scan (Non Destructive)

The Device Scan feature enables the analysis of block devices to determine their compressibility and fill levels, offering valuable insights into storage efficiency, performance potential, and wear characteristics.

Benchmark (Destructive)

The Benchmark feature tests a block device’s performance through write-intensive, destructive tests, designed for unmounted or unused volumes. Customizable parameters like block size, read/write ratios, and compression levels provide detailed metrics to help optimize storage performance.
