Recently, I found myself in a situation where I required an external backup device that could utilize both Firewire or USB 2.0 interfaces, while also being portable and having over 300 GB+ of storage space.

Thanks to the rather large proliferation in digital media such as music, video and high resolution photographic images many users now find themselves in the situation where more storage space is needed as their existing hard drives fill up with media. External hard drives have always been ideal in these situations, and they’re also very cheap and fast enough to backup entire hard disks in reasonable time.

As I’m about to rebuild my PC which currently has IDE hard disks, these drives won’t connect to the motherboard on my new machine, actually they will but it’s not worth the hassle. So I required an external device to backup the important data on my hard IDE disks, and then I could simply copy it over to the new PC, which requires SATA hard disks.

Upon scouring Amazon UK, I found the perfect solution, it was black and had a green or blue ring of light, similar to the Xbox 360. The Western Digital My Book Premium came in two versions, a USB 2.0 only drive called the My Book Essential, which featured the green ring of light, and a USB 2.0 and Firewire version featuring a blue ring of light, which was the Premium model. As I prefer to use Firewire for data transfer, I opted for a 320GB Premium and its blue ring of light, shame this type of model featured blue rather then a green ring. Amazon had the 320GB USB/Firewire model at just £99 which was a real bargain.

I was up and running inside 2 minutes with the drive. Just hook up the medium sized (thank god for that!) power brick which is about the length of your average mobile phone, then attach either the USB or Firewire cable to your computer and off you go!

Its name derives from the fact that Western Digital vision this device as a book. I could see where they were going with that, it is roughly the size of a book…with a ring of light! It does look great sitting on your desktop though. The green/blue ring of light indicates drive activity by rotating in a circular fashion as data is accessed or written to disk. The centre of this ring is a button for manually starting/shutting down the unit. There aren’t other controls on this device, not that it really needs any given its purpose.
