Which is logical, since it is currently the most popular interface in modern technology. In addition, there are old-style interface IEEE 1394 (FireWire) interface and the new sample eSATA – very 'young' from all external interfaces parsed us. The average practical rate of the interface is higher than that of USB 2.0 and IEEE 1394 (FireWire) – is a plus. Also an advantage is attributed the fact that, unlike IEEE 1394 (FireWire), eSATA is an option connector, which makes it the same universal, as well as USB 2.0. The main disadvantage at the moment (early 2009) – a 'youth' standard, so it is not enough spread in the vast majority of computers. But it is also worth noted that the presence of all these advantages is preparing for a great future, and eSATA is quite possible that this interface will soon be number 1, not only as an external interface to an external hard drive, surpassing even making the first steps of USB 3.0 in front of him with superior speed.

Design. Because the content and about the same interfaces, each producer is fighting for its buyer, working on the design of the device, resulting in then run up your eyes, because external hard drive can be, for example in plastic, metallized, rubberized, even a leather case. Variations of colors cover the entire body the color spectrum, and, of course, size, are actually very important because HDD Form Factor 2.5 inch should have such a property as compactness. Additional options. Well as additional incentives for the purchase of, some external hard drives equipped with special options. As an example button on the HDD, when clicked, backs up data from an external hard drive to hard drive. Set delivery. And varies with the product.

Some of the Internet – shops offer drives with a special cover for transportation, which will retain the appearance of an external hard drive, and sometimes may save data during a fall. In addition, virtually all manufacturers bundle their external hard drives, an exclusive software, which is designed to facilitate the work with the data. Depending on the software, you can: synchronize mailbox, compress and encrypt data, create hard disk partitions, which will be password protected and has many different functions. The disk with the software usually comes in the kit, in extreme cases the software can be downloaded from the manufacturer. Thus, each user will be able to find the hard drive to your taste, both in terms of design, and in terms of features and applications. And it pleases. How to build your website.
