What is a hard disk drive?
Hard disk drive (HDD) is the basic non-volatile storage drive that is used for storing and retrieving digital data. HDD has rotating platters coated with magnetic material with reading/write heads that access the data while the platters are spinning. Hard drives are most commonly found in PCs, laptops, consumer electronics, and enterprise storage systems. The reading and writing of the hard disk are controlled by hard disk drives that offer data storage. Hard drives are connected to the motherboard via various cables including advanced technology attachment (ATA), serial ATA, Parallel ATA, or small computer system interface (SCSI) cable.
What is a solid-state drive?
A solid-state drive (SSD) is a new generation of storage device that is used to store data on interconnected flash memory chips. The files in the solid-state drive are saved on a grid of NAND flash cells in which each grid can store between 256 KB and 4MB. SSDs are typically faster and reliable as compared to HDDs. They are mostly found in the latest systems and high-end machines like the Apple MacBook Pro and other expensive laptops. The solid-state drives are basically used by businesses and enterprises that work with large amounts of data (such as programming environments or data analysis). Moreover, the gaming industry also utilizes SSDs because games constantly load and write files (e.g. levels, maps, textures, and characters).
