Long before the first laptop arrived on the market, the idea behind the ready. Back in 1968, a "personal, portable information manipulator" was thought by Alan Kay at Xerox PARC, and this idea was detailed in his 1972 paper, as the "Dynabook."
A few years later, back in the early days of mobile computing, a "portable computer" was about 20 pounds, and no hard disk, because the storage was typically provided by double 5A ¼ "single-density floppy drives. That's obvious - to the 1870s, was too early for laptop hard drives, but do not worry ... We get it immediately!
In 1982, when The clamshell design was first introduced in a portable computer, the hard drive still out, but since 1983, the term "laptop" starts being used, and all fast hard drives were also introduced, along with CD-ROM drives).
Now we actually have two generations of the current hard drives in laptops - the classic hard disk, and the SSD. A few years ago, I remember that some hybrid systems were also introduced in some high-end laptops, designed to help save energy and increase boot times, using a flash memory / HDD Some classic, but because it's actually not just go, let's talk about what we could call this moment "laptop hard drives, "shall we?
Currently, most laptops have 2.5-inch or 11.8-inch hard drives, while the desktop of its 3.5-inch models. Their rotation speed is typically, 5400 or 7200rpm, and they have at least 8MB buffer memory, and up to 500GB.
Some producers in the laptop market drives are not popular in the desktop drives one, as if Toshiba. It is noteworthy that in the past two years, many laptop hard drives prices fell, allowing easy upgrades / replacements (easy on budget, you know ...).
At last we have solid state drives, also known as SSDs, with capacities from 4GB to some netbooks, and 128GB. Obviously, this solution is expensive, but we could see SSD completely replacing the traditional hard drive in a few years.
