It was only a matter of time. The Terabyte drive is about to ship. What is a Terabyte drive? I hear you ask. In simple terms, it’s big, it’s really big, it’s the size of Texas! In practical terms it is a hard drive that you can store about 1000 full length movies on.

A Terabyte is 1000 Gigabytes.

Hitachi has announced a Terabyte drive that will be shipping very soon at a price of less than $400.

Hard drive technology has grown in leaps and bounds. The original technology was developed by IBM 50 years ago. When it hit the streets a 5 megabyte (5 million characters) drive retailed for approximately $75,000. Needless to say this was not something that the average person would buy.

The story of the hard drive has very much mirrored the story of silicon technology. In 1964 Gordon Moore, co-founder of Intel announced to a somewhat skeptical world that it was his opinion that silicon technology would advance at a rate where the number of components that could be squished onto a given area of silicon would double every 18 months! This effectively doubles the speed of a computer every 18 months. Well Gordon Moore’s prediction has stood the test of time. It is now 40 years later and it is still happening. The phenomena is referred to as Moore’s Law.

Hard drive technology while not silicon based has followed Moores Law, in fact the doubling of capacity time frame is about 16 months.

You can also be reasonably confident that about this time next year that one terabyte drive will be selling for around $100 and no longer being manufactured.
