    4.50 / 5

Pros

  • Extremely fast transfer speeds, backwards compatible with USB 2.0

Cons

  • Lacks bundled software, no eInk display or capacity gauge

Bottom Line

If you're after speed, the My Book 3.0 external hard drive will certainly deliver. However, you'll pay a premium for the USB 3.0 interface, and there's no backup software or eInk display for labelling.

Would you buy this?

Western Digital's My Book 3.0 is its first external hard drive with a SuperSpeed USB 3.0 interface, making it one of the fastest direct-attached storage devices around. The benefits of the interface are certainly noticeable, though the premium price will deter early adopters.

The My Book 3.0 has the same sleek, book-like casing as Western Digital's other current My Book external hard drives. Unfortunately, it has neither the My Book Elite's eInk display nor the Essential's capacity gauge. Instead, the My Book 3.0 has a simple white indicator light. Although attractive, it's rather useless.

The casing is passively cooled through the top, which makes for quiet operation; the drive is audible when it operates over the USB 3.0 interface, however.

The My Book 3.0 has a SuperSpeed USB 3.0 interface

The main drawcard of the My Book 3.0 is its SuperSpeed USB 3.0 interface, which promises transfer speeds of up to five gigabits per second (Gbps), or 10 times USB 2.0's theoretical speed limit. Since the hard drive itself is limited to a maximum speed of 3Gbps, the My Book 3.0 won't quite reach those speeds. In real world operation, Western Digital claims you should see speed increases of four to five times those of USB 2.0 drives.

There aren't many PCs that currently have USB 3.0 connections, but the interface is backwards compatible with USB 2.0 (the My Book 3.0 will simply operate slower). For an extra $30, you can pick up a bundle that includes the external hard drive and a PCI Express 2.0 adapter card that provides two USB 3.0 ports for your desktop PC.

At $249.99, the Western Digital My Book 3.0 is $70 more than its USB 2.0-equipped counterpart, or $100 more if you buy the bundle kit. Once formatted, you'll get 931GB of usable space, making for a cost per formatted gigabyte of 26.8c; pricier even than Seagate's BlackArmor WS 110.

Disappointingly, you won't get any bundled software with the My Book 3.0; just USB 3.0 drivers and electronic manuals.

Performance

In order to see how the Western Digital My Book 3.0 external hard drive would fare under a variety of circumstances, we used two testbed PCs. For tests with vanilla USB 2.0 transfers and using the USB 3.0 expansion card, we used a PC equipped with a Core i7-965 CPU, 6GB of DDR3 memory and 300GB Western Digital Velociraptor hard drive, running Windows Vista 64-bit. For our primary USB 3.0 file transfer benchmarks, we used the same Velociraptor system drive but swapped out the motherboard for an ASUS P7P55-DE Premium motherboard, which boasts both SATA 6Gbps ports and an integrated USB 3.0 controller. The second PC was equipped with a Core i5-750 processor, clocked at 2.66GHz.

Our test files include a 3GB batch of 1MB files as well as a 20GB folder of 3-4GB files.

In initial tests, the My Book 3.0 increased file transfer speeds by roughly three times when connected to a USB 3.0 port. Our in-depth benchmarks show similar results; a My Book 3.0 external hard drive directly connected to a USB 3.0 port will easily surpasses USB 2.0 by three to four times, and compete with other fast interfaces such as eSATA, which has a theoretical speed ceiling of 3Gbps.

The external hard drive was much faster when connected directly to the USB 3.0-capable motherboard than when using the bundled expansion card. Since PCI Express 2.0 cards have a speed limit of 4Gbps, the speed differences are likely due to the host controllers used. Still, when using the bundled expansion card, you are likely to see a significant speed boost over vanilla USB 2.0 and, in many cases, over eSATA, too.

There's no doubt USB 3.0 is the future: it's capable of greater speeds than eSATA and has other benefits like being hot pluggable and delivering power to portable hard drives. The My Book 3.0 external hard drive is an excellent example of the interface's capabilities, though lacks some of the features of Western Digital's more stylish storage options.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

As a freelance writer who is always on the go, I like my technology to be both efficient and effective so I can do my job well. The HP OfficeJet Pro 8730 Inkjet Printer ticks all the boxes in terms of form factor, performance and user interface.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
