Blazing Fast External Hard Drive

How fast is fast enough when dealing with data transfer? When you’re dealing with backups or copying large files from one drive to another, you can never have too much speed. The new USB 3.0 spec emerged last year. The speed comparison between a USB 2.0 drive and a USB 3.0 drive is staggering. Fortunately, the costs have dropped and adding a USB 3.0 external hard drive to your computer has become an attractive idea.

USB 2.0 and USB 3.0 Speed Comparison

The leap in throughput was as substantial in USB 3.0 as it was between USB 1.0 and 2.0. With the newer USB 3.0 specification topping out near 5 Gbps, it is faster than the wired computer networks in most homes.

Investing In USB 3.0

Because the standard is relatively new, your computer may not have a USB 3.0 card installed. Motherboards will eventually ship with USB 3.0 on-board, but if your computer only has the older USB 2.0, then you’ll need to purchase a USB 3.0 card. The cable is also different. So there will be some investment costs in upgrading, but the price is minimal in comparison to the huge performance boost you’ll get after upgrading.

This USB 3.0 hard drive from Buffalo is said to out-perform internal hard drives. It is an external drive and would be great for moving massive amounts of data back and forth between computers or even just being used as a standard backup hard drive. It is backward compatible with USB 2.0, but you will want to invest in the USB 3.0 card to get the maximum performance. As with most external hard drives, this model also ships with its own cable, so you will not need to purchase the new USB 3.0 cable.

In Conclusion
As file sizes and hard drives get larger and larger, the time it takes to backup and copy data will increase. Having a USB 3.0 hard drive in your computer will eventually become a necessity.
