What is a Hard Drive?

So what is a hard drive?  It in the only internal component in a computer currrently that have storage without electricity.  hard drive topAlthough the BIOS in the computer maintains information it still uses the battery on the motherboard to do so.

Without a hard disk in a computer, anytime the power would flicker, or you would have to reboot, you would lose everything.  A hard drive contains a large amount of storage where any other software is installed to.  When you open a program or file, it is usually read from a hard disk then held within RAM. 

A hard disk stores information like a tape drive, all the information is magnetically stored.  The inside of the drive contains what looks like several compact discs stacked on top of each other with a small brush riding on each side of each disc.  This brush is moved back and forth to get to any part of the disc as it spins.

The Best Hard Drive

If you have not picked a SSD hard drive, you will need at least one of the drives below.

WD Black 1 TBicon - Standard drive for any computer, fast and reliable.

WD Black 2 TBicon - For those who need some extra storage.

TIP! If you want a solid state drive for the speed, there is an alternative, the sata raid.  This is my current personal choice.

Choosing a Hard Drive

To choose a hard drive, I will take a look at reviews, although not as big of a deal unless this is going to be your primary hard drive.  Next be sure and check reviews and make sure that you have a compatible connector on your motherboard.
