The size of today?s hard drives boggles the mind. 40GB is the norm and disks ten times that size are emerging. Coupled with this surge in disk capacity is an explosion in file sizes. Ten years ago, the average drive contained mainly word documents, each a few KB in size. Now, multi-MB PowerPoints, MP3s and PDFs litter the hard drive. The problem is that drive I/O speed has not kept up the pace. As a result, it has developed into a serious bottleneck in system performance. Consider the facts: Processor speeds are measured in billions of operations per second; memory is measured in millions of operations per second; yet disk speed remains pegged at hundreds of operations per second. This disparity is minimized as long as the drive?s read/write head can just go to a single location on the disk and read off all the information. The huge gulf in speed between a disk and the CPU/memory is a severe problem when the disk is badly fragmented. File fragmentation not only lowers performance, it leads to a catalog of woes such as slower virus scans and backups, databases corruption and premature hardware failures. This concise paper discusses how fragmentation affects today?s larger hard drives and files sizes, what this does to the system as a whole, and how this crippling bottleneck can be eliminated automatically on every server, workstation and laptop in the enterprise using automated defragmentation software.
