4. Intel Rapid Storage Technology (IRST)

The IRST software package enables and enhances high-performance Serial ATA (SATA) and SATA RAID capabilities for supported operating systems. The IRST software package provides an added protection against data loss in the event of a hard-drive failure.

  • NOTE: The following conditions must be met before you can install IRST on your computer.
    • Your computer has a RAID I/O controller hub (ICH). If your computer does not have a RAID ICH, you cannot install IRST unless a third-party RAID controller card is installed.
    • Your RAID controller is enabled by default.
      • CAUTION: If a SATA hard drive is already installed, enabling the RAID controller might cause your computer to display a blue screen and an error code followed by a system reboot. To enable RAID, reinstall the operating system.
