Hard Drive Comparison- What is Hard Disk Drive?

Reviews

The hard disk drive(sometimes abbreviated as Hard drive, HD, or HDD) is the main, and usually largest, data storage hardware device in a computer. A Hard drive is a non-volatile memory hardware device that permanently stores and retrieves data on a computer.The operating system, software titles, and most other files are stored in the hard disk drive.

The hard drive is sometimes referred to as the “C drive” due to the fact that Microsoft Windows designates the “C” drive letter to the primary partition on the primary hard drive in a computer by default. A hard drive is a secondary storage device that consists of one or more platters to which data is written using a magnetic head, all inside of an air-sealed casing. For example, some computers have multiple drive letters (e.g,. C, D, and E). The amount of information a hard drive can hold is usually measured in Megabytes (MB’s) or more often these days Gigabytes (GB’s). They also have some servers that use hard disk’s that hold massive amounts of information that amount to Terabytes (TB’s).

Because SATA is still fairly new, they are generally more expensive than PATA drives because of there faster speeds and newer technology used.This hard drive is basically a magnetic disk enclosed in a metal casing that spins. It kind of works like a cd in a cd player. When you request information to be retrieved from the disk, the read/write heads on the drives locates and find the wanted data and then transfers it to the system’s memory where it is held until either the user terminates it or the computer is shut off. The hard disk is a very important component in the computer system. Without this component, there would be no working computer system.

There are also Seagate External Hard Drives that you can purchase, in both desktop and portable models that you can take with you wherever you go, which is great for that information you just don’t want to keep on your main hard drive. Use them to back up your data and / or store movies and pictures on them so not to take up space on your main hard disks!

solid-state drive (SSD) is a solid-state storage device that uses integrated circuit assemblies as memory to store data persistently. SSD technology primarily uses electronic interfaces compatible with traditional block input/output (I/O) hard disk drives (HDDs), which permit simple replacements in common applications. New I/O interfaces like SATA Express and M.2 have been designed to address specific requirements of the SSD technology.

Hard disk drive (HDD) began to be SSD (SSD) replacement because of the distinct performance advantages they have over HDD, including faster access times and lower latency.While SSDs is becoming more and more popular, but HDDs continue to be used in many desktop computers largely due to the value per dollar that HDDs offer over SSDs. However, more and more laptops are beginning to utilize SSD over HDD, helping to improve the reliability and stability of laptops.
