WHAT IS ITUSBs’ can store several Gigabytes of

data. They are usually connected to the computer through USB ports and power

is taken from the computer to make them work. They are extremely small and

portable. Most operating system recognize them consequently no

additional software is requires

WHAT IS IT………………….

Holographic data storage is a potential technology in the area of high-capacity data storage currently dominated by magnetic and predictable optical data storage. Magnetic and optical data storage devices rely on individual bits being stored as different magnetic or optical changes on the surface of the recording medium.

By Black Mambas

ADVANTAGES OF HOLOGRAPHIC DATA STORAGE:

• Long Durability – The Holographic data storage disk can last for at least 50 years.

• Extremely useful for medical archiving. (magnetic storage devices typically have storage life of 5 years).
