One of the biggest drawbacks in the currently available portable external hard drives is their low speed compared with the regular internal hard drives. While some internal hard drives reached the rate of 15k RPM spindle speed, the top-performing external hard drive still spins at 5,400 RPM, and this is for a valid reason. Just like any mechanical device, a hard drive is not so vibration-proof, therefore if it’s subjected to an intense shock, it’ll very likely go out of action. To work around this problem, the portable external hard drive manufacturers have to decrease the spindle speed to a lower level, and that would make it more stable and more vibration-resistant than if it runs at a higher speed rate.
What can be an exception of that is what happened a few months ago, when HGST made a bold move by releasing their Touro S 7200RPM High-Performance Portable Drive, a very fast external portable hard drive that spins at 7200RPM, and implemented their own techniques to fortify and immunize it against the bad effects of vibration. But still, for the sake of maintaining the stability of their product, they could not exceed the 1TB capacity limit, while other manufacturers have reached 4TB already.
That’s why if your main concern is the high speed, you cannot dispense with an external solid state drive, as they are currently the fastest portable backup solutions available. Otherwise, if you want a good compromise between speed, capacity and price, try to get one of the premium portable external hard drives listed below.
But why do you want an external hard drive in the first place?.. Well, An external hard drive has three main purposes: to expand your computer’s storage capacity, to back up your data, and to share data between computers. It’s also easy to use. Most of the time, you just need to plug it into the computer and use it as an internal hard drive. Portable external hard drives are based on the 2.5-inch internal hard drives.
