Best Hdd Docks 2017

When we buy a new laptop today, the customer service representative of the store may ask him whether models with a hard disk drive (HDD) or SSD (Solid State Drive). One of the major differences between SSD and HDD is that SSD has no moving parts. Hard disk stores information inside a rotating disk. Read / write head sits directly over this dish and when it spins, reads and writes data. Looks a bit like the old record player. SOLID state drive, however, stores data inside a little microchip , and the memory block must not move to provide information to the computer.

The continuous nature of the SSD makes it faster than a hard drive; user can get instant access to information with built-in CPU, SSD , instead of having to wait until his hand is going to read and review. Computers that use hard disks can handle, but fast SSD drives. The speed of hard drive depends on how quickly his plate rotates, and many computer manufacturers are currently creating those that can boast of up to 7200 rpm. Some hard drives based on the server there are plates that rotate up to 15,000 rpm.

You may wonder what are the advantages of one of these types of units of memory over the other. Hard drives are usually cheaper than SSD. A lot notebook hard drive has about 1 TB or 1024 GB of memory, but SSDS typically have 512 GB or less. Prices are always changing, but computer-based hard disk can cost fifty percent or less than the price of the same model of hard drive of the same capacity. In this regard , through the use of technology NAND flash , the manufacturers of the computers with SSD processors hope to increase the capacity of their products while maintaining low prices, trying to be more competitive against the PCs hard drives.

History of hard drives
When hard drives first appeared on the market, they were very expensive. IBM released in 1953. And betrayed it in 1956. His name is IBM 305 RAMAC and has 5 megabytes of data costs $ 10 000 per megabyte. RAMAC has been a large using 50 24-inch disks to store data. A few years later, IBM created a flying head, which hovered over the magnetic disks of the hard disk, reading and writing information. And only in 1963, IBM produced the first external hard drive that was much less than their original model. This removable hard disk is consisted of six 14-inch dishes and could accommodate up to half of the data first model.

These primitive hard drives were very bulky and they moved slowly, so in 1973, IBM released its hard disk hard drive, which had lubricated spindle for faster file access, and low mass heads who did not occupy so much space. IBM was the only major manufacturer of hard drives, as long as the company called Seagate Technology began to produce them in 1979. Then IBM and Seagate seemed to be in a race to spend better and faster product. In 1980, IBM released its first Gigabyte hard drive, and in the same year, Seagate introduced the first 5.25-inch hard disk. Other hard disk manufacturers appeared on the market at this time, including Western Digital, Shugart Associates, and Rodime.

Shugart created the interface, which was the first small computer system interface (SCSI) in 1981. In 1988 Appeared a 1-inch to 3.5-inch hard drive, which still is the standard format for computers. In 1991, IBM created the first disk with the heads magnetorezystywnymi (MR), and in 1992. Seagate stole, releasing the first 2.5-inch hard drive, which has become a standard laptop size HDD. Seagate again zaszokowałoby the tech world when they released the first disc is capable of up to 15,000 rpm in 2000.

What makes that station hard drives is unique
There are a total of nine internal hard drives , but only two that are currently active, 2.5 and 3.5-inch. Some stations hard drives can read these sizes. A docks with the hard drive, even a card reader SD and XD, so are useful in almost every computer task, from gaming to photo viewing.

Some people have internal hard drives that they want to protect your computer all the time. Docking station makes sure you don’t have to remove the internal hard drive to have the opportunity to work with an additional. Internal hard drives can overheat and crack the inside of your computer. The docking station allows the user to periodically create a backup disk, internal, thereby not losing all data in case of their destruction.

Most docking stations can also read one hard drive while writing to another. This enables a user to simultaneously work on the files contained on a single hard disk on your computer, while adding a data in another. Some models even have cloning technology in the Autonomous mode, which allows the user a great up data and saving them to another drive without erasing the original.
