How to Enable Advanced Disk Performance in Windows Vista

August 17th, 2008 | by admin |

Windows vista is the latest Operating system by microsoft having tons of improvement and security updates as compare to windows XP.Advanced Disk Performance is also another good feature in windows vista.

By default Windows Vista reads from a cache on your hard drive and writes directly to the hard drive, bypassing the cache. Reading and writing from your hard drive’s cache is much faster than from it’s platters. When you enable advanced performance on your hard drive it reads and writes from your hard drive’s cache making some operations faster.

When Advanced Disk Performance is enabled, the hard disk drive operates in write-back cache mode, in which all the data that gets written to the drive is first stored in the cache, and then later written to the disk. Both writes and reads are cached in this case. When disabled, the HDD operates in write-through cache mode, in which all data that gets written to the drive is immediately written to the disks and also stored in the cache. Writes are not cached, but reads are.

Note: This setting is recommended only for disks with a backup power supply, it further improves disk performance, but it also increases the risk of data loss if the disk loses power.

How to Enable Advanced Disk Performance
Open Device Manager, expand Disk drives, right-click on a Disk drive, click Properties, click the Policies tab, select the Enable advanced performance check box, and then click OK.
