Hard Drive Speeds

Many people don’t realize that the slowest part of their computer is the hard drive. The read and write speeds of a hard drive affects the computer’s performance. The most affected processes are the boot time and time it takes to open an application.

Experiment

I decided to explore the speed differences between several types of hard drives. In all the trials I used a program called Parkdale for speed measurements. *Please note that these are just the hard drives I had lying around, there can be great variation of performances between different manufacturers.
