Remember the days when the word Google was not interchangeable with internet? Or when every site seemed to have a Netscape icon on it? Or when Flash was still something you cleaned your floor with? Then you were clearly using the web in the mid to late 1990s when pages were rudimentary affairs containing lists of links and information.

The drive to smaller form factors is made possible by continuing advances in electronics, disk media, read/write heads, and other disk drive technologies - all of which provide the ability to store ever more data on a given disk surface area. Historically, technology advances have resulted in the doubling of areal density - and thus the megabyte capacity of a disk - about every 18 months.

Amazing facts and figures about the evolution of hard disk drives

Microsoft ex-CEO Bill Gates predicted that as PC users evolve into "knowledge navigators," the demand for mass storage speed and capacity will continue to outpace technology developments. Gates speaks with authority as the mastermind behind dozens of PC applications and the leading PC operating environment, Microsoft Windows, all of which require increasing amounts of storage at higher levels of performance. As just one example, a complete installation of Microsoft Word, with its built-in spell checker, thesaurus, and grammar checker, now occupies 24 MB of hard drive space - more than two times the entire hard disk drive capacity of the original IBM PC/XT. Emerging applications such as multimedia, which requires storage of video images, demand even more hard drive capacity and performance. For example, a single frame of video can comprise over 4 MB of data. Given that "true motion" video operates at 30 frames per second, it's not hard to understand how a multimedia application can easily devour a gigabyte of storage. The remainder of this book will familiarize you with mass storage options, and the hard disk drive in particular, one of the most vital components of the modern computer. You will learn about computer systems, disk drives, and other forms of mass storage. Finally, this book looks into the future to highlight new technology developments that promise to keep hard disk drives revolutionizing our lives for years to come.

The evolution of the floppy disk starts with the IBM 23FD introduced in 1971.

With the introduction of the IBM PC/XT in 1983, hard disk drives also became a standard component of most personal computers. The descriptor "hard" is used because the inner disks that hold data in a hard drive are made of a rigid aluminum alloy. These disks, called platters, are coated with a much improved magnetic material and last much longer than a plastic, floppy diskette. The longer life of a hard drive is also a function of the disk drive's read/write head: in a hard disk drive, the heads do not contact the storage media, whereas in a floppy drive, the read/write head does contact the media, causing wear.

By design, hard disk drives contain vastly greater amounts of data than floppy disks and can store and retrieve it many times faster. Rapid declines in price for hard disk drives meant that by the mid-1980s, a drive of at least 20 MB capacity was a standard component of most PCs. (Because floppy diskettes are a cheap and removable storage media, floppy drives still are included in most PCs as a means for loading software and transporting and archiving vital data.)
