Post -- 414. Is That a Terabyte in the House?

Is That a Terabyte in the House?

My Youngest Son just ordered a Terabyte Drive from NewEgg for about $100 bucks. My Oldest Son just recently bought his Second 2 terabyte drive that's 4 TB (terabytes of storage) in his house.

My biggest portable storage device is a 16GB (gigabyte) thumbdrive about half the size of a pack of certs.

It cost $40.00.

So the Question I get most often is:

What IS a Terabyte?

210 single-layered DVD's in 1 Terabyte (TB)

650 to 702 MB to standard CD

Single-layer DVD capacity is 4.7 GB

Blu-ray capacity is 25 GB or 0.025 terabytes

For DVD Dual-layered Media, just Double the Numbers above.

History of CDs and DVDs:


Several years after the introduction of the CD, two consortiums started pushing a new standard for a higher-capacity optical media: the MultiMedia Compact Disc, backed by Philips and Sony, and the Super Density disc, supported by Toshiba, Time Warner, Matsushita Electric, Hitachi, Mitsubishi Electric, Pioneer, Thomson, and JVC. With a clear memory of the 1980s’ VHS–Betamax video-format wars, IBM’s president, Lou Gerstner, led an effort to unite the two camps behind a single standard. The attempt was a success: the MultiMedia Compact Disc was abandoned in favor of the SuperDensity Disc, becoming the digital videodisc or versatile disc, today known simply as DVD. The new format was supposed to hold 5GBs of data, but Philips and Sony insisted on a different version of encoding, reducing the disc density to a more familiar 4.7GBs—still more than seven times that of a CD. It took several years for the new format to mature, but in late 1996 Toshiba, Matsushita, Sony, and several other companies released the first DVD players in Japan, reaching the U.S. several months later. The first players cost more than $700 on their release, and the first computer DVD recorder, the Pioneer DVR-S10, hit the market in late 1997 with a whopping list price of $16,995.
