About External Hard Drive

All computer owners know that disk space never seems to be enough, no matter how great the capacity is. Fortunately, there are many external hard drives available on the market to help those that are in constant need of more space. This same problem has also inspired the trend of storing data online, but the speed of the Internet cannot match the one of simply plugging in a hard drive and reading directly from it. The speed of an external hard drive is very dependent on its connection type. The most common is the USB 2.0 that allows for data to be transferred at 480 Mbps, which is quite decent. However, with the rise of the drive's capacity, this speed might be insufficient as it can still take a long time to transfer the whole content. USB 3.0 is the next obvious choice. Though it is not as widespread as the 2.0, this technology is backward compatible, so a 3.0 drive can be jacked in any USB. Through a 3.0 port, the data can be transferred at speeds up to 10 times greater than those of the USB 2.0. The Thunderbolt port developed by Intel allows for a transfer even greater than that but it is not largely implemented. It might be rare and costly but it allows a fast 10Gbps transfer rate. There are some additional features on an external hard drive that can make your life easier. Models that have a network port make it easier to share the data, so they are always regarded as a good option. There are even some advanced models with embedded streaming software and a HDMI port for easy movie access. If portability is the largest concern, always choose a model that does not require an additional power supply cable.
