Storage Device Command

A Storage Device Command is a hardware-level command that instructs storage devices to perform specific operations.

• AKA: Storage Command, Disk Command, Drive Command, Storage Controller Command, Device Control Command.
• Context:
  • It can typically be issued through Storage Interface Protocols such as ATA, SCSI, or NVMe.
  • It can typically control Storage Device Operations including data access, device configuration, and maintenance tasks.
  • It can typically require Administrative Privileges or elevated permissions for execution.
  • It can often be vendor-specific or follow industry standard specifications.
  • It can often interact with Storage Controller Firmware for command processing.
  • It can range from being a Read/Write Storage Device Command to being a Management Storage Device Command, depending on its command function type.
  • It can range from being a Standard Storage Device Command to being a Vendor-Specific Storage Device Command, depending on its command specification source.
  • It can range from being a Synchronous Storage Device Command to being an Asynchronous Storage Device Command, depending on its command execution mode.
  • It can range from being a Non-Destructive Storage Device Command to being a Destructive Storage Device Command, depending on its data preservation status.
  • It can integrate with Storage Management Software for automated execution.
  • It can support Storage Security Features through security-related commands.
  • ...
• Examples:
  • Storage Device Security Commands, such as:
    • ATA Secure Erase Command for data sanitization.
    • ATA Security Freeze Lock Command for write protection.
    • NVMe Sanitize Command for NVMe device sanitization.
  • Storage Device Management Commands, such as:
    • SMART Command for device health monitoring.
    • TRIM Command for SSD optimization.
    • Format Command for device initialization.
  • ...
• Counter-Examples:
  • File System Command, which operates at logical level rather than hardware level.
  • Operating System Command, which manages system resources rather than storage hardware.
  • Application Command, which controls software functions rather than device operations.
