September 2006 marked the 50th Anniversary of the disk drive. When IBM delivered its first hard drive, 13 September 1956, few could imagine the impact on our daily lives. The RAMAC (also known as "Random Access Method of Accounting and Control) was the size of two refrigerators and weighed a ton. A separate compressor on the head, a pizza-sized protect dishes and was able to save an enormous Hat and 5 megabytes of data. Now you canAll this can be done with a simple portable player! What's more - the RAMAC was for rent for £ 18,500, equivalent to € 134.500 pounds immediately available.
25 years later, the first hard drives for personal computers were invented. With the MFM encoding method has a capacity of 40 MB and 625 kbps data rate. A later version of the transition to ST506 RLL encoding method interface that a larger memory capacity and processing speed.
IBM made technological history12. August 1981 with the launch of the first personal computer - IBM 5150th At a price of £ 830 to 5150 only had 16K memory, enough for a small amount of e-mail. It is hard to imagine that recently were considered at the end of the year 1980 to 100 MB of disk space to be sufficient. In a time of day it would be more than enough, enough to install the operating system, not to mention a large application like Microsoft Office.
When asked about the limits offirst PC, Tom Standage, executive director of the magazine The Economist said: "It's hard to imagine that people used to do with computers, because in these days of modern standards, they could not really do anything."
Because of these important advances, the industry of thousands of DVDs in 1950 to more than 260 million readers per year in 2003, has risen. During this period, has decreased the cost of magnetic disks as storage media from € 1088 per megabyte in 1960 to 0.03Pence today.
The future is bright
Currently, the device may default desktop 3.5 "up to 750 gigabytes (GB) of data. But hard drives are getting smaller, more powerful and cheaper. According to Bill Healy, an executive at Hitachi, records with hundreds of gigabytes is small enough to be worn as jewelry. "You have with you all the albums and songs you've ever bought, every picture you have taken, every tax record."
Afterfive units of the nuclear family is increasingly common: desktops, laptops, gaming consoles, VCRs, call TiVo ®, iPod ® - just few of them. Experts believe that one day, families, up to 15 plates, some of which appear on television, mobile phone or car.
In fact, the industry's largest number of disks in the next five years would generate, as in the past 50 years. Industry analysts such as Gartner, IDC and TrendFOCUS believe that the hard drive in the worldMarket will continue to experience impressive unit and revenue growth.
Take the good and bad
What new devices on the market, and the amount of data increases the risk of data loss is more than ever. No matter how closely the back-up policy, or what will take place the burden of investing in the protection of data somewhere in the loss of on-line. With 20 years of experience, Ontrack Data Recovery ™ certainly had their share of the data by the disaster. OfMemory Stick dog eats a man - the user so angry, frustrated, he shot his laptop with a gun! Not to mention the business woman who spilled coffee on his laptop and his father, who accidentally deleted the photo of the child's mention of his son.
