Ten Reasons to Defrag Disk Drives Cheat Sheet (DRAFT) by [deleted]

This is a draft cheat sheet. It is a work in progress and is not finished yet.


Files on your computer can either be fragme­nted, like newspaper articles, or unfrag­mented, like a book. Over time, more and more files become fragme­nted. When a file is fragme­nted, it takes longer for the computer to read it because it has to skip to different sections of the hard disk drive.

Defrag­men­tation is a process that rearranges and reasse­mbles your files on your hard disk


1. Defragging provides more “up time” by saving your machines from excessive drive head activity. This extends hardware life another 1- 2 years.
2. Savvy VARs have defrag­menters on their servers not just for the margins, but because they can’t afford not to. Those on service contracts lose money each and every time they take a Support call. And many of those calls are from fragme­ntation related issues like system slows or even drive failures. Defragging eliminates those calls altoge­ther.
3. One file one scan. One thousand fragmented files one thousand scans. Thus defragging cuts long anti-virus scans nearly in half. The same applies to back up times. It’s a simple numbers game: the more fragme­ntation you have, the more you suffer.
4. Load times for Office docs like Word, Excel and Outlook show a hefty return in speed after defrag­ging. Boot times can also be sped up by defragging the MFT file. And even web browsing is sped up 2 – 3X from a good defrag of the Internet cache. Remember, the more fragme­ntation you have, the more you suffer.
5. Defragging busy file/S­QL/­Exc­hange servers increases network traffic speeds by freeing up I/O bottle­necks.
6. A defrag­menter is the most inexpe­nsive perfor­mance enhanc­ement you can make—far cheaper than memory or hardware upgrades.
7. Even when you have the fastest CPU and memory availa­ble—a machine’s perfor­mance is negatively affected by fragme­nta­tion. Why? Because the disk drive is still the slowest component in a computer. And as the saying goes, “A computer is only as fast as its slowest compon­ent.” Defragging the drive is thus essential to all computers, old and new.
8. Automatic defraggers make your job easier by taking the guesswork out of schedu­ling.
9. The tenth and possibly best reason to defrag is your time. Your free time, your family time and your work time. So to spend your time on better things, embrace an automatic defragger.
10. Server virtua­liz­ation may reduce the number of physical systems for more efficient CPU utiliz­ation. But think about it: consol­idating five servers into one means you’ll have 5X the traffic and 5X the levels of fragme­ntation now taking place on a single server. So to keep that virtual machine from joining the Titanic, routine defragging is essential to optimum perfor­mance and uptime.
