What Is Mass Storage Devices and Their Types

Mass Storage refers to the storage of large amounts of data in a persisting and machine-readable fashion. Mass storage includes devices with removable and non-removable media. It does not include RAM, which is volatile in that it loses its contents after power loss. Mass storage devices are characterized by:

•Sustainable transfer speed
•Seek time
•Cost
•Capacity

Types Of Mass Storage Devices

1.Floppy Disk Drives(FDD)

2.Hard Disk Drive(HDD)

Floppy Disk Drive (FDD)- A floppy disk is a data storage medium that is composed of a disk of thin, flexible ("floppy") magnetic storage medium encased in a square or rectangular plastic shell. Unlike most hard disks, floppy disks are portable, because it can remove them from a disk drive. Disk drives for floppy disks are called floppy drive. Invented by IBM, floppy disks in 8-inch (203 mm), 5 1/4" in (133 mm) and 3 ½‖ in (89 mm) formats enjoyed nearly. There decades as a popular and ubiquitous form of data storage and exchange, from the mid 1970’s to the late 1990’s. the floppy disks current role is in these area- 

1.Data transfer 

2.Small storage and backup 

3.Software installation and driver updates 

Hard disk drive (HDD)- A hard disk drive (HDD) is the mechanism that controls the positioning, reading, and writing of the hard disk, which furnishes the largest amount of data storage for the PC. The seek time of HDD is about 12 milliseconds or less. There are several interface standards for passing data between a hard disk and a computer. The most common are IDE and SCSI. Significant role of hard disk are following 

1.Performance 

2.Storage capacity 

3.Software support 

4.Reliability
