Storage device

A storage device is a hardware device designed to store information. There are two types of

storage devices used in computers; a 'primary storage' device and a 'secondary storage' device.

Primary storage device

Also known as internal memory and main memory, primary storage is a storage location that

holds memory for short periods of times while the computer is on. For example,

computer RAM and cache are both examples of a primary storage device.

Secondary storage device

Also known as external memory and auxiliary storage, secondary storage is a storagemedium that holds information until it is deleted or overwritten regardless if the computer has

power. For example, a floppy disk driveand hard disk drive are both good examples ofsecondary storage devices.

When we talk about the storage devices; there are many types and different kinds of storage

devices are available. The classification may be different for the different types of the storage

devices. The storage devices can be volatile or non volatile.

Flash Storage Devices

Flash Storage is pretty much same as solid storage devices. The main deference is flash storage

is designed for more portability. Flash storage comes is smaller sizes. Pen drives and memory

cards are the example of flash storage.

Flash drive is designed to be external to the computer system, an SSD is designed to reside inside

the computer in place of a more traditional hard drive. They are non volatile in nature. Flash

Memory is also called Flash Memory. Flash Memory is also used as secondary memory in some

ultra portable computer as well as PDAs.

USB FLASH STORAGE

disk (1 to 4 inches ) and most USB Flash Drive weigh less than an ounce .

HARD DISK DRIVES

Ahard disk drive] is a non-volatile storage device for digital data. It features one or more rotating rigid

platters on a motor-driven spindle within a metal case.

The hard disk is housed inside the hard drive, which reads and writes data to the disk. The hard drive

also transmits data back and forth between the CPU and the disk. When you save data on your harddisk, the hard drive has to write thousands, if not millions, of ones and zeros to the hard disk. The

information stored to the hard disk remains even the power is turned off.

Cisco Systems today announced the launch ofCisco Smart Storage , its first line of networked-

attached desktop storage devices aimed at businesses with fewer than 100 employees.

Ray Boggs, an analyst with market research firm IDC, said Cisco's entry into the storage device

market is part of a larger industry trend of networking or data center companies attempting to be all

things to their customers.

"Netgear has gone down that road already, as has HP , where you have a network communications

company getting involved in storage," he said. "It speaks to the blurring of a lot of this technologywhere storage is associated with security, which is associated with the Internet, which then gets you

into networking.

Cisco's new Small Business NSS 300 Series Smart Storage series consist of two-bay, four-bay and

six-bay desktop network storage boxes with up to 12TB of capacity based on 2TB SATA drives.

The NSS 300 Series Smart Storage supports file sharing and backup for Windows, Mac, and Linux

platforms and can be set up in a variety of RAID configurations including RAID 0, 1, 5, and 6 (dual-
