While lower-priced laptops still come with traditional, cheaper hard drives, most mid-range to high-end machines come with an SSD. Solid state drives require less power, which translates into better battery life. SSDs are often used in laptops because they're non-mechanical. SSDs: SSDs are newer types of disks that store information on flash memory, which consists of individual memory cells storing bits that are instantly accessible by the controller. Since all of these pieces are вЂњmechanical,вЂќ the hard disk is the slowest and most fragile component of any computer. Data is written and read by a fast-moving head, similar to the way vinyl record albums work.

The direction of the magnetization represents the individual bits.

HDDs: In an HDD, an enclosure contains a series of platters covered by a ferromagnetic coating. While SSDs and HDDs are both storage devices, the way they work is quite different. The laptop on the left above comes with a traditional hard disk drive, while the one on the right has a more modern solid state drive. Today, when you buy a new PC, you have two very different options: you can get one with an SSD or one with an HDD. Until the late 2000s, when you bought a new hard disk drive or personal computer, your hard disk storage choices were limited to size and speed - perhaps 5,400 or 7,200 rotations per minute.
