Seek speed may also be mentioned, as this is rate at which the device sources your files. Upload speed is measured in megabytes per second (MB/s), and again the more the better with 100MB/s being an attractively fast speed. Most devices tout times of: 7200 RPM, 5400 RPM and 4200 RPM, with 5400 RPM being the most common. How fast is fast? Well the short answer is the higher the number the faster the transfer and upload rate, for example 7200 rpm is quicker than 5400rpm.
SpeedĬalculated by how quickly the discs inside the drive spin, a hard drive’s operational speed is quantified in RPM (rotations per minute). Firewire, similar to the USB in its plug and play operation, but is available in two speeds: Firewire 400 (which matches the performance times of most USBs) and the faster version Firewire 800 which is mainly compatible with Macs. USB, the predominantly used connection variant, simply plug in and your computer should detect it automatically. There are two main ways to connect an external hard drive to your machine USB and FireWire. It is also worthwhile knowing that although you think you are buying say ‘250GB’ of space, as much as 30GB of that could be taken up with pre-installed files such as for virus protection and operating software, etc from the manufacturer – so you never quite get as much space as you think you will. With 250GB of space, photographers will easily be able to store up to 80,000 images (depending on resolution), so a terabyte will provide room for around 320,000 – much more than many will need. Ideally opting for something around the 250GB gives you the best of both worlds and should only set you back £40 ($60).

The range of capacity is vast you’ll find everything from a USB pen storing as little as 1GB of information (which may enough for the very casual photographer) to larger data backs offering 2TB or more (perhaps more than even the most professional shooter will need). As mentioned in Part 1 you can pick up a ‘cheap’ 1TB for around £60, but this isn’t necessarily the best deal as purchasing several slightly cheaper yet lower capacity units will reduce the risk of lost files if your one and only external hard drive breaks. This refers to how much information your device can hold in the same way a memory card or your computer’s hard drive does. Below you’ll find some short explanations to help you get started. Shopping for a suitable product may seem like a complete headache, especially if you are unsure of what specifications are good and which is average.

In this section of our backing up series (read part 1 at Backing Up and Saving Your Images) we look at external hard drives, which are arguably one of the most cost effective and simplest ways to store your images.
Save it, store it, back it up and back it up again – if you work by this, you may never have to experience that tummy churning sensation of remorse.
