The Evolution of File Storage

PHYSICAL STORAGE VS. DIGITAL STORAGE Recording information is an inherent part of our humanity. As we evolve, we create more efficient means of storing this information. Since the creation of computers, we have greatly increased our ability to store and access large quantities of information. Take the storage of music, for example. 12" 10" 4TM 4.7" ДИ 2 MINUTES 6 MINUTES WAX CYLINDER 10" RECORD 1880s 1910s 44 MINUTES 46 MINUTES 12" RECORD 8-TRACK TAPE 1930s 1960s 60-90 MINUTES 80 MINUTES .. 19705 CASSETTE TAPE COMPACT DISC 1980s Compare that with modern digital storage. 60 MINUTES 1 HOUR First-generation 5GB iPod 12" RECORD x 159 In 2001 Apple introduced the 5GB iPod.

We are beginning to move into an age where any movie or TV show we wish to watch is accessible online. Large VHS or DVD collections are no longer necessary as more entertainment is at our fingertips. We are also abandoning traditional rental services in favor of services, like Hulu and Netflix, that offer streaming content on the web. 50 Company Stock Price 40 VHS 3,5 HOURS NETFLIX O 30 20 4 HOURS DVD 10 BLOCKBUSTER• 2005 2009 IF YOU TAPED EVERY MOVIE ON HULU BACK TO BACK ON VHS TAPES YOU'D NEED 259 TAPES THERE ARE 20 HOURS OF VIDEO UPLOADED ON YOUTUBE EVERY MINUTE THAT'S 343 TAPES UPLOADED EVERY HOUR B00888888688868I B0ECBCEC88888880BEB08800E 18888888 What about storing photos?
