One of the largest challenges for any IT firm is data storage, as the communication between various entities in a software company increases and the data grows in bounds. The need for offline storage is basic to manage data processing and to maintain the data backup. There are several mediums of storage that are chosen depending upon size of the industry, bandwidth, cost and environment. Most of the organizations are in need of storage devices to enhance their efficiency in storing large amount of data. There are hard disk storage drives, solid state drives, floppies, zip drives, tape drives, Storwize, autoloaders and many more. All these devices are used externally according to the requirement. These are directly connected to the servers to increase the storage capacity.
Hard disk is a traditional variant of disk drives, which is composed of thin magnetic plates mounted in a cylindrical style. These are axed on spindle motor, and are enclosed with protective cover. Data is magnetically read or written on to the disk with help of heads that float on the disk layer. Data in the disk is identified using physical address; disk controller is responsible for mapping logical address into physical address. The disk is physically divided into cylinders, tracks, sectors and disk head points to specific sector of the disk, this activity is termed as seek time. Mostly disk storage is used to storage permanent data, meaning that data should be non-volatile. When it comes to storage area, it occupies very less space compared to tape storage and comes in very less price.
Hard disk storage is a must for any physical system since it is the main source of data storage including operating system. Also, it is built with memory buffers that help in caching when there are high-speed data operations need to be performed on the disk. Data in the disk are stored in form of fragments and sometimes-read operation will be slow since these fragments are scattered. To avoid this, OS performs defragmenting action on disk to separate used and free sectors.
In some cases, set of disks are clubbed to form large backup systems. Backup paradigm such as RAID makes use of hard disks upon which they employ control to form a single unit of storage. It has higher usage life compared to other storage mediums and rate of reliability is high. Also, the disks are easily portable by which the hard disk from one system can be plugged out and plugged into other system with no much overhead. Hence, these are useful to manage the massive amount of data.
