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. When you enable advanced performance on your hard drive it reads and writes from your hard drive’s cache making some operations faster.
This tutorial will show how to speed up your hard drive by turning advanced performance.
Warning: It’s only recommended to enable advanced performance on laptops or computers with redundant power supplies or battery backups. If your computer suddenly looses power you could corrupt or lose data.
