DATA STORAGE DEVICESFlor Estefanía Hernández Gómez
ZIP DISK A zip disk is a computer hardware device that stores data. A zip disk drive is somewhat like floppy disk drive, only that the size of disks inserted into the devices are different. Where a normal floppy disk can hold about 1.44 megabytes of data, a zip disk can hold around 100 megabytes of data
3.5~INCH FLOPPY DISKA floppy disk is a disk storage medium composed of adisk of thin and flexible magnetic storage medium,sealed in a rectangular plastic carrier lined with fabricthat removes dust particles. They are read and writtenby a floppy disk drive (FDD).
MINI DVD MiniDVD is known also as "3 inch DVD", referring to its approximate diameter in inches. A MiniDVD can be played back in most Blu Ray and DVD players that are tray loaded. The trays on players and DVD drives have an inner ring where the 8 cm disc is centered for loading in the player. Most slot loading players cannot use this format; there are exceptions, however, such as the PlayStation 3 and the Wii, but not the Wii U. Both officially support 8 cm discs
CD~RW A CD-RW (Compact Disc-ReWritable) is a rewritable optical disc. It was introduced in 1997, and was known as "CD-Writable" during development. It was preceded by the CD-MO, which was never commercially released. CD-RW disc require a more sensitive laser optics. Also, CD-RWs cannot be read in some CD-ROM drives built prior to 1997. CD-ROM drives will bear a "MultiRead" certification to show compatibility.
MINI CD Mini CDs, or “pocket CDs” are CDs with a smaller diameter and one third the capacity
DVD~RW A DVD-RW (Rewritable Less) is a rewritable DVD which can record and erase the information several times. The standard capacity is 4.7 GB. It was created by Pioneer in November 1999 and is opposed to format DVD + RW, further supported by Panasonic, Toshiba, Hitachi, NEC, Samsung, Sharp , Apple Computer and the DVD Forum.
TAPE DRIVE A tape drive is a data storage device that reads and performs digital recording, writes data on a magnetic tape. Magnetic tape data storage is typically used for offline, archival data storage. Tape media generally has a favorable unit cost and long archival stability.
COMPACT FLASH (CF) Is a mass storage device format used in portable electronic devices. Most CompactFlash devices contain flash memory in a standardized enclosure. The format was first specified and produced by SanDisk in 1994. The physical format is now used for a variety of devices
MINI MMC is a storage device that retains information that has been stored correctly even with the loss of energy, that is, memory is a memory card volátil. is a memory chip that holds its content without power
FLASH MEMORIES is a non-volatile computer storage chip that can be electrically erased and reprogrammed. It was developed from EEPROM (electrically erasable programmable read-only memory) and must be erased in fairly large blocks before these can be rewritten with new data. The high density NAND type must also be programmed and read in (smaller) blocks, or pages, while the NOR type allows a single machine word (byte) to be written or read independently.
SECURE DIGITAL (SD) is a non-volatile memory card format developed by the SD Card Association (SDA) for use in portable devices. The SD technology is used by more than 400 brands across dozens of product categories and more than 8,000 models.
TRANSFLASH O MICRO SD is the most common used memory card in mobile phones and the SD Card Association’s objective is to make microSD a de facto memory card standard for all mobile phones. All TransFlash and microSD cards always come with a SD Memory Card adaptor, which makes them compatible to all SD Memory Card slots. The microSD is about 10% in volume compared to SD Memory Card and about 30% compared to miniSD
SMART MEDIA (SM) is a flash memory card standard owned by Toshiba, with capacities ranging from 2 MB to 128 MB. SmartMedia memory cards are no longer manufactured.
MULTIMEDIA CARD (MMC) is a flash memory memory card standard. Unveiled in 1997 by SanDisk and Siemens AG, it is based on Toshibas NAND-based flash memory, and is therefore much smaller than earlier systems based on Intel NOR-based memory such as CompactFlash. MMC is about the size of a postage stamp: 24 mm × 32 mm × 1.4 mm. MMC originally used a 1-bit serial interface, but newer versions of the specification allow transfers of 4 or 8 bits at a time
XD is a flash memory card format, used mainly in older digital cameras. xD stands for Extreme Digital. xD cards are available in capacities of 16 MiB up to 2 GiB
MEMORY PEN (USB MASS STORAGE) is an industry standard developed in the mid-1990sthat defines the cables, connectors andcommunications protocols used in a bus forconnection, communication and power supplybetween computers and electronic devices
