Floppy Disk
A floppy disk is a disk storage medium composed of a disk
of thin and flexible magnetic storage medium, sealed in a
rectangular plastic carrier lined with fabric that removes
dust particles. They are read and written by a floppy disk
drive (FDD).

Floppy disks, initially as 8-inch (200 mm) media and later
in 5.25-inch (133 mm) and 3.5-inch (89 mm) sizes, were a
ubiquitous form of data storage and exchange from the mid-
1970s well into the first decade of the 21st century
Zip Disk
The Zip drive is a medium-capacity removable disk storage
system that was introduced by Iomega in late 1994.
Originally, Zip disks launched with capacities of 100
MB, but later versions increased this to first 250 MB and
then 750 MB.

The format became the most popular of the super-floppy
type products which filled a niche in the late 1990s portable
storage market
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.

A tape drive provides sequential access storage, unlike a disk
drive, which provides random access storage. A disk drive can move to
any position on the disk in a few milliseconds, but a tape drive must
physically wind tape between reels to read any one particular piece of
data. As a result, tape drives have very slow average seek times. For
sequential access once the tape is positioned, however, tape drives can
stream data very fast. For example, as of 2010[update] Linear Tape-
Open (LTO) supported continuous data transfer rates of up to 140
MB/s, comparable to hard disk drives.
Mini CD
Mini CDs, or “pocket
CDs” are CDs with a
smaller diameter and one
third the capacity
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.
DVD-RW

A DVD-RW disc is a rewritable optical disc with equal
storage capacity to a DVD-R, typically 4.7 GB. The format
was developed by Pioneer in November 1999 and has been
approved by the DVD Forum. The smaller Mini DVD-RW
holds 1.46 GB, with a diameter of 8 cm
MiniDVD (Mini DVD or miniDVD) is a DVD disc having
8 cm in diameter.

The 8 cm optical disc format was originally used for music
CD singles, hence the commonly used names CD single and
miniCD. Similarly, the manufactured 8 cm DVDs were
originally used for music videos and as such became known
as DVD single.

xD-Picture Card is a flash memory card format, used
mainly in older digital cameras. xD stands for Extreme
Digital.[1]

xD cards are available in capacities of 16 MiB up to 2 GiB.

Flash Memories
Flash memory 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) es un formato de tarjeta de memoria
inventado por Panasonic. Se utiliza en dispositivos portátiles
tales como cámaras fotográficas digitales, PDA, teléfonos
móviles, computadoras portátiles e incluso videoconsolas (tanto
de sobremesa como portátiles), entre muchos otros.

Estas tarjetas tienen unas dimensiones de 32 mm x 24 mm x 2,1
mm. Existen dos tipos: unos que funcionan a velocidades
normales, y otros de alta velocidad que tienen tasas de
transferencia de datos más altas. Algunas cámaras fotográficas
digitales requieren tarjetas de alta velocidad para poder grabar
vídeo con fluidez o para capturar múltiples fotografías en una
sucesión rápida.




SD
A USB flash drive is a data storage device that includes flash
memory with an integrated Universal Serial Bus (USB) interface.
USB flash drives are typically removable and rewritable, and
physically much smaller than a floppy disk. Most weigh less than
30 g.[1] As of January 2012 drives of 256GB were available,
512GB and 1 terabytes (TB) drives were in planning,[2] [3] and
storage capacities as large as 2 terabytes are planned,[4] with
steady improvements in size and price per capacity expected.
Some allow up to 100,000 write/erase cycles (depending on the
exact type of memory chip used)[5] and 10 years shelf storage
time.[6][7]




Memory pen
A memory card or flash card is an electronic flash memory
data storage device used for storing digital information.
They are commonly used in many electronic
devices, including digital cameras, mobile phones, laptop
computers, MP3 players, and video game consoles. They
are small, re-recordable, and able to retain data without
power.




Flash Card
SmartMedia 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.




Smart Media
CompactFlash (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.[4] The physical format is now used for a variety of
devices




Compact Flash
The MultiMediaCard (MMC) is a flash memory memory
card standard. Unveiled in 1997 by SanDisk and Siemens
AG, it is based on Toshiba's 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. It has been more or less superseded by SD
(Secure Digital) card, but still sees significant use because
MMCs can be used in most devices that support SD cards.
