An USB 2.0 external hard drive is one of the best inventions of the latest decade. However, as you have a large number of options on the market, it is important to know the characteristics of such a hard drive, in order to find the best one for your needs.
An USB 2.0 external hard drive is necessary for any person that has a laptop, considering that the programs, games and different files are larger now. The calculation is simple. If you are the fan of new games and latest software solutions offered by companies, you will probably need to benefit of a larger hard disk capacity. Sure, your internal hard might be large enough, but sometimes it is needed to copy large files from one computer to the other, and in this case, only an USB 2.0 external hard drive could help you.
The USB 2.0 external hard drive benefits of increased performances compared with the oldest versions of hard drives, as they are cheaper, and the transfer speed is surely superior. In fact, this is the most important characteristic of an external hard drive: the transfer capacity. Sure, the total storage space is also important, but as we are talking about a portable device that is needed for many transfers, the speed of transfer is far more important.
Of course, the price is also an important characteristic of the USB 2.0 external hard drive, but the price also depends on the speed of transfer and capacity.
The USB 2.0 external hard drive is the classical hard disk you have in your computer, with the difference that it is placed in a case, and that it can be connected to any device with an USB connection.
The USB 2.0 external hard drive that can be used for mini laptops are also known under the name of racks, and if you find such a device in a store, you should know that it is the same device.
Now that we have determined what is an USB 2.0 external hard drive, you should determine the reliability of the connection of this device with your computer.
The technical data of the USB 2.0 external hard drive is composed of the capacity of the device, the rotation speed, and also the manufacturing company. The USB 2.0 connection is recommended if you are looking for a hard disk for backup. There are other two types of connection, the Firewire and the eSATA, but those are older external hard drives that will probably disappear from the market soon.
Tips and comments
If you are looking for an USB 2.0 external hard drive to store Blu-Ray movies and multimedia applications, you should look for the new 3.0 USB connection. However, this is an improvement of the classical USB 2.0 connection, so the devices based on this connection are more expensive.
Of course, it is also important to determine the resistance of the USB 2.0 external hard drive, as we are talking about an external device that will be carried around all day long. Eventually, your hard disk will be supposed to shocks and bumps, so you should make sure it has a resistant case.
