How much storage is on a 1 Terabyte on a hard disk?
Saturday, February 28th, 2009
1TB, or Terabyte. That’s 1,000,000,000,000 bytes of information! A byte is one character, say the letter “c” or “x”.
So, how much is that in real life?
I still have a 40 Megabyte hard disk in my collection from 10 or 15 years ago. I actually forgot when I got it. And, that was HUGE at the time. It cost a couple of hundred dollars to boot.
If we can assume that storing text from an average magazine page uses one byte per character, one page would equal about 5000 characters.
That means my old 40 MB hard disk was able to hold about 900 pages.
Now, lets fast forward to today when you can buy a 1 TB hard disk for under $100 on sale.
My new 1 TB hard disk would hold a whopping 220 million pages!
To use another analogy, a DVD movie averages 6 Gigabytes, or about 136,000 pages. I can fit between 100 and 125 DVD quality movies on a 1TB disk. I could fit 250,000 high quality digital photographs on it. Or, more than 200 million mp3 music files. Don’t tell the kids.
Guess what? Most people who use a digital camera or video camera can fill that up in no time.
With all of the digital content we collect today, music, documents, software, videos (Youtube and our own), is it any wonder that our information truly is more valuable than the machine we store it on?
That “IS” the best reason in the world to back up you data. But, that’s for a future story.
