Support for 4k Sector Disks

Intel® Rapid Storage Technology (Intel® RST) version 9.6 and newer supports 4k sector disks if the device supports 512 byte emulation (512e). Intel RST does not support 4k native sector size devices.

What happens if I try to use an older version of the driver?

If you try to install the operating system on a 512e disk with a driver older than Intel RST version 9.6, the install process might not complete.

If the operating system does install, do not try to upgrade to Intel RST version 9.6 without reinstalling your operating system.

How do I install the operating system on a 512e storage device?

RAID

If your system has a supported RAID controller, follow these steps to install the operating system on a 512e device:

  1. Download the latest driver files.
  2. Use the Load Driver method to load the driver during operating system install.

AHCI

If your system has a supported AHCI controller, you do not need to load the Intel RST driver during the operating system. If you choose to manually load the driver, load Intel RST version 9.6 or newer.
