When you begin to work with hard drives, it is important to understand what a hard drive is and what it is made of. What are the components that make up a hard drive? How does this impact how you use them? In this video, join instructor Kevin Ames as he walks you through the pieces that make up a hard drive.
- It's been said that the beginning…is a very good place to start.…And when it comes to hard drives,…what's in a hard drive is that very good place.…We have to understand how they're made…and what they do internally…so that we can understand how to protect them from failure…for as long as possible.…So what's in a hard drive?…The first component is the spinning platter.…The platter is where the data is stored.…It's written by the read-write head,…and these two interact.…
What happens is the spinning platter…is running between 5400 RPM…or 7200 RPM.…That means, in a 7200-RPM drive,…the edge of the platter…is traveling at about 67 miles per hour.…It's been suggested by people that they just speed up…the platter spin on the hard drive…to be able to get a faster read-write.…They said, "Well, why don't they go to 20,000 RPMs?"…Well, at that speed, the edge of the platter…is hitting close to the speed of sound,…which would tear the drive apart.…
The read-write head moves across the platter…and seeks out where each segment of data is written.…
