Other than the overall price, there are a couple of other things that you should look out for when buying a portable hard drive. So before you take a look at our Top 10 best portable hard drives chart, you may want to quickly find out what to look out for when buying a portable hard drive.
First of all is the type of the drive in the portable hard drive, it's easy to think that bigger is better, but you should also consider whether the hard drive is an SSD (solid state drive) or a spinning HDD (hard disk drive). An SSD is likely to be more expensive, but the benefits of this are that it will be significantly quicker than a HDD as there are no moving parts in a solid state drive.
Once you've decided whether you want an SSD or a HDD portable hard drive, it's always worth checking out the devices actual read/write speeds before you make a decision, as these vary wildly from model to model.
Equally important in terms of speed is what type of connection is on offer on the portable hard drives. In 2013 you really should be looking to buy a portable hard drive that is USB 3.0 compatible as it can deliver up to 10 times faster transfer speeds than USB 2.0. Alternatively if you have a computer that supports Firewire connections then you should look out for a portable hard drive that supports these connections also as it offers extremely fast transfer speeds too. Mac users will want to look out for a Thunderbolt port.
