A solid-state drive contains one or more inflexible

What is a solid-state drive?

A solid-state drive does not contain one or more inflexible, circular platters that use magnetic particles to store data, instructions, and information. Instead, it uses flash memory technology.

What is the difference between a hard drive and a disk?

A (n) ____ hard drive is a self-contained unit that you insert in and remove from a slot or USB port in a device or a computer. A disk ____ consists of a special-purpose chip and electronic circuits that control the transfer of data, instructions, and information from a disk to and from the system bus and other components in a computer.

What is a solid-state drive (SSD)?

The SSD (solid-state drive) is a technology that has been around for more than 30 years but remained too expensive for broad adoption. That changed with the introduction of consumer products such as the Apple iPad and iPhone, which led to the widespread availability of cheap nonvolatile memory.

What is the difference between NAND flash and SSD?

The most common SSD configuration is eight channels, but an SSD controller can have 4-32 channels to meet performance requirements. NAND flash has higher performance but also a higher bit error rate than other storage media. The higher error rate requires the SSD to correct bit errors at gigabytes per second, equivalent to the speed of NAND flash.

How do SSDs work?

Most SSDs are built around widely available NAND flash memory, developed in the late 1980s as an electron-based trapped-charge storage media. The NAND cell stores electrons on a capacitor indefinitely in a no-power state. The charge is then sensed by circuitry on the NAND chip.
