Portable USB 3.0 Drives

External hard drives have arguably become one of the most sought after storage devices in recent years. The portable ones are fast gaining popularity; a recent market survey showed a large number of choice portable drives with different storage capacities available for a “few cents per GB”. Portable drives can be a savior, but that notwithstanding, can also screw everything up if something goes wrong.

The following are a few advantages and disadvantages of portable drives.

Advantages

• Cost effective: Portable drives are a better option over CDs, DVDs and Blu-rays for someone who needs long term storage.
• Storage Space: A 4TB hard drive costs just $100, providing the owner with a large storage space for a small amount.
• Copy Speeds: Advancements have seen copy speeds on drives reach as much as 10Gbits/s.
• Portability: Travelling, but you don’t want to go with that PC of yours? A portable drive is the best bet. Simply plug and play and you’re good to go.
• Plug and play: You don’t need to write a long string of commands on your PC for your portable drive to run. Many portable devices are plug and play enabled.

Disadvantages

• Prone to theft: This is one major disadvantage of portable drives. Data can fall into the wrong hands when these portable hard drives are stolen.
• Prone to easy damages: Portable drives are much more prone to damages when they fall, are exposed to unfavorable temperatures or are accidentally unplugged during transfer operations.
• Overheating: Unlike internal computer storage drives which have a cooling fan next to it, portable hard drive manufacturers in a bid to make them as portable and as lightweight as possible haven’t found a permanent solution to the issue of overheating in portable drives.

Enough said about their advantages and disadvantages.

Advancements in technology and a variety of specifications have led to the availability of a large number of USB 3.0 drives in the market today.

Why USB 3.0? What about USB 2.0? What’s the difference?

The journey of USB 3.0 began sometime in 1998 with the creation of the USB 1.1 which had very slow data transfer rates. Two years later, the USB 2.0 was introduced and the USB’s data transfer speed leap frogged to 480Mbits/s. It became a standard for many USB enabled devices designed up until 2008 when the world heralded the birth of the USB 3.0 with data transfer rates of about 5Gbits/s.

Incredible, right? It didn’t stop there. There’s the all new USB 3.1 introduced in 2013 as an upgrade for the USB 3.0’s speed, placing it at par with the first version of Thunderbolt. The good thing is that each USB class is backward compatible with its predecessors except of course the USB 3.1 which isn’t backward compatible with the USB 1.1.

The USB 3.0 has become a standard for majority of the USB devices in the market today. Its edge over its predecessor are highlighted below:

• Faster transfer speeds
• Dual unidirectional data transfer paths where each path carries data in one direction and the other in the reverse direction leading to increase in data transfer speeds unlike the USB 2.0 with only one direction data transfer path.
• The USB 3.0 provides 900mA of power as against the under 500mA provided by the USB 2.0.

Portable hard drive manufacturers have embraced the USB 3.0 technology as they outdo each other to produce some of the best the world has ever seen. As earlier stated, these portable hard drives come in various specifications which can either make it very expensive or less expensive. The SSDs (Solid State Drive) is a typical example. It’s high end and pretty pricey.
