A storage device is a device that allows for the recording or storage of information or data. This can be a disk drive, removable media card, or other portable device that contains data for archiving purposes or future use.Magnetic Storage is a term referring to the storage of data on a magnetized medium. Magnetic storage uses different patterns of magnetization in a magnetizable material to store data. It is a non-volatile form of memory. Magnetic storage is primarily used for hard disk drives.Optical Storage is a term referring to the storage of data on an optically readable medium. Data is recorded by making marks in a pattern that can be read back with the aid of light, usually a beam of laser light, precisely focused on a spinning disk. An example of optical storage is a CD.nikongrossary
A high-speed network that connects computer storage devices, such as hard drives and tape libraries, to servers. A SAN allows multiple computers to access a centralized pool of storage. Files can be shared, copied, or moved quickly and efficiently on a SAN.
How much storage capacity will be needed for video? The following are based on the ITU-R BT.601 4:2:2 digital coding standard for SD, given that every line of 625/50 or 525/60 TV has 720 luminance (Y) samples and 360 each of two chrominance samples (Cr and Cb), for a total of 1,440 samples per line. 625/50 format: 21 Mbytes of storage for each second of video. 525/60 format: 21 Mbytes per second, or 76 Gbytes per hour. If the video is compressed, divide the numbers by the compression ratio. HD 1080 x 1920 format, using 4:2:2 sampling: 560 GB per hour.
A compact memory storage device used to store data captured by a digital camera. Storage card formats include CompactFlash (CF), Secure Digital (SD), xD, SmartMedia, and Memory Sticks.
