Which utility program could improve the speed of disk ?

The benefits of defragging hard disk drive are

1. Faster Applications

Programs run faster and more efficiently when the data is grouped together for easier access.

2. Extended Hard Drive Life

The mechanical parts of the drive have to travel less distance when the data is all in one place, thereby increasing fast access to files and reducing wear and tear on the drive itself.

3. More Efficient Security

When an antivirus program scans hard drive, it takes less time when drive is less fragmented.

4. Reduced Errors

The process of defragmentation can often point out bad sectors that could potentially cause damage if data was saved in this area.
