Summary: Difference Between Hard Disk and Solid State Drives is that a hard disk is a storage device that contains one or more inflexible, circular platters that use magnetic particles to store data, instructions, and information. A solid state drive (SSD) is a storage device that typically uses flash memory to store data, instructions, and information. Hard DiskA hard disk is a storage device that contains one or more inflexible, circular platters that use magnetic particles to store data, instructions, and information. The system unit on most desktop and notebook computers contains at least one hard disk. The entire device is enclosed in an airtight, sealed case to protect it from contamination. A hard disk that is mounted inside the system unit sometimes is called a fixed disk because it is not portable. With respect to a storage medium, the term portable means you can remove the medium from one computer and carry it to another computer. Current personal computer hard disks have storage capacities from 160 GB to 2 TB and more. Home users store documents, spreadsheets, presentations, databases, e-mail messages, Web pages, digital photos, music, videos, and software on hard disks. Businesses use hard disks to store correspondence, reports, financial records, e-mail messages, customer orders and invoices, payroll records, inventory records, presentations, contracts, marketing literature, schedules, and Web sites. Traditionally, hard disks stored data using longitudinal recording, which aligned the magnetic particles horizontally around the surface of the disk. With perpendicular recording, by contrast, hard disks align the magnetic particles vertically, or perpendicular to the disk’s surface, making much greater storage capacities possible. Experts estimate that hard disks using perpendicular recording provide storage capacities about 10 times greater than disks that use longitudinal recording. Hard disks are read/write storage media. That is, you can read from and write on a hard disk any number of times. Solid State DrivesA solid state drive (SSD) is a storage device that typically uses flash memory to store data, instructions, and information. With available sizes of 3.5 inches, 2.5 inches, and 1.8 inches, SSDs are used in all types of computers including servers, desktop computers, and mobile computers and devices such as portable media players and digital video cameras. Storage capacities of current SSDs range from 16 GB to 256 GB and more. SSDs have several advantages over magnetic hard disks.
The disadvantages of SSDs are they currently have a higher failure rate than hard disks, and their cost is much higher per gigabyte. As the price of SSDs drops, experts estimate that increasingly more users will purchase computers and devices that use this media.

A hard disk drive, hard disk, hard drive, or fixed disk is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage and one or more rigid rapidly rotating platters coated with magnetic material. A hard disk is a storage device which stores data on rapidly rotating platters with magnetic surfaces. Many hard disks are internal hard disks within the computer's chassis and cannot be removed. Floppy disks Floppy discs are basically circular disks enclosed within a plastic square jacket with the circular disk having a magnetic oxide coating. These can be characterized as Magnetic storage devices that allow easy handling of data. Hard disks use magnetic disks to store data and instructions in tracks and sectors. A track is a narrow recording band that forms a complete circle on the disk's surface. Which of the following storage device is magnetic disk type?hard disk is a storage device that uses rigid, permanently installed magnetic disks to store data. it is a magnetic disk on which you can store data . it uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks.
What is a round disk which stores information?DVDs are circular flat optical discs used to store data. It comes in two different sizes one is 4.7GB single-layer discs and another one is 8.5GB double-layer discs. DVDs look like CDs but the storage capacity of DVDs is more than as compared to CDs.
What forms circles on the surface of a hard disk?Tracks, Sectors, and Cylinders
Disk platters are formatted in a system of concentric circles, or rings, called tracks. Within each track are sectors, which subdivide the circle into a system of arcs, each formatted to hold the same amount of data—typically 512 bytes.
Which is a circular disk which can store a large amount of data?Hard disk is an hardware component which is used to store large amounts of data. The primary characteristics of hard drive are its capacity and performance.
