The Intel® Application Accelerator replaces the ATA drivers that come with Windows* with drivers optimized for desktop and mobile PCs using select Intel® chipsets. It reduces the storage sub-system bottleneck, enabling the processor and other system level hardware to be more productive and efficient. It is not a requirement for your operating system to work properly.
