Intel® Solid-State Drive Toolbox User Guide Tuning your System Running System Tuner Use the System Tuner to check your system and adjust settings to improve the performance, power, and endurance of the selected Intel SSD. If your system requires tuning, the following icon appears next to System Tuner on the home screen: To run the System Tuner: 1. Select the Intel SSD on the home screen. 2. Click System Tuner. The System Tuner displays services that can be optimized for use with the selected Intel SSD. If a service is available and can be optimized, Tune! appears next to the service name. • Intel® Rapid Storage Technology (Intel® RST) Write Cache For best performance, Intel recommends enabling Write Back cache in Intel® RST/Intel® Matrix Storage Manager console. Note: This service appears on the System Tuner screen only if your system has an Intel® RST RAID volume configuration containing only Intel SSD RAID volume members. • Superfetch*/Prefetch In Microsoft Windows* 7 and Windows Vista*, Superfetch* tracks and copies your most frequently used applications to system memory to reduce load times. Superfetch is based on the similar Prefetch feature available in Windows XP. Superfetch/Prefetch is not needed on an Intel SSD and should be disabled for optimal performance. • ReadyBoost* In Microsoft Windows Vista, ReadyBoost is a feature that uses any flash memory device connected to your system as a drive for disk caching. It is also used to facilitate SuperFetch. In Windows 7, ReadyBoost is part of SuperFetch. In Windows XP, ReadyBoost is not installed. ReadyBoost is not needed on an Intel SSD and should be disabled for optimal performance. • Device Initiated Power Management (DIPM) For Intel SSDs installed in mobile systems, DIPM is the most efficient power management method for managing SATA link power. With DIPM, link management is handled by the SSD (the SSD knows best how long a specific command might take to complete and is best equipped to request a link power management state change while processing the command). DIPM should be enabled on Intel SSDs for optimal performance. • Defragmenter Microsoft Windows Disk Defragmenter rearranges files stored on a disk to occupy contiguous storage locations to increase access speed and optimize the time it takes to read and write files to and from the disk. In Windows 7 and Windows Vista, Disk Defragmenter should be disabled on Intel SSDs. In Windows XP, Disk Defragmenter cannot be disabled. In this operating system, make sure to unschedule Disk Defragmenter on any Intel SSD(s). Intel® Solid-State Drive Toolbox User Guide 22 September 2011 Order Number: 325912-001US
