SOLID STATE DRIVE VS HARD DISK DRIVE SERIES
SSD has no mechanical arm, to write and read information, but instead relies on an embedded processor, or “brains” or controller, which performs a series of operations associated with reading and writing data. Typical SSD is based on NAND flash memory, a type of nonvolatile memory, so you can turn off the drive, and it will not “forget” what is stored on it. Rising from the comfort of your couch to retrieve a book from the bookshelf, or that same book magically appearing in front of you? In the same way, we can compare the HDD with an SSD. In comparison, which is faster SSD or HDD? That is the reason why the SSDs are much faster.
The data on the SSD are stored in microchips, while hard drives use a mechanical arm for reading / writing data. Most of you are familiar with the USB memory and SSD is sophisticated version of USB sticks. Even though everyone is using the word “disk”, SSD actually has no disc or any mechanical (moving) parts. Solid-State Drive is also a device for permanent data storage that gets written and read through integrated circuits. After shutting down your computer, data remains on the disc. As the plate rotates faster and faster data is processed on a hard drive. The “needle” floats above the rotating plate and reads and writes data. Hard drives use magnetism to store data on a rotating disk. Yes, you read that right, hard drive technology is almost sixty years old.
Hard disk drive (or hard drive, fixed disk, HDD) is a technology pioneered by IBM in 1956. Share Tweet In this article we will explain the differences between HDD and SSD devices and show advantages and disadvantages of both technologies.
