Western Digital RE4-GP (WD2002FYPS) 2TB hard drive
Western Digital's greenest enterprise internal hard drive is a good performer
- GreenPower technology lowers power consumption, quiet, minimal vibration, fast
- Operating temperatures are comparatively high, idle power consumption doesn't meet expectations
While slightly more expensive than a consumer drive, the Western Digital RE4-GP will save on power bills in the long run and it has a sizeable cache.
Price$ 469.00 (AUD)
Western Digital's RE4-GP (WD2002FYPS) internal hard drive offers most of the energy-saving features of the company's Caviar Green line of consumer drives, but it also includes server-friendly features such as reduced vibration and noise. Though more expensive than a Caviar Green drive, the RE4-GP's lower power consumption and improved performance make it worth the extra outlay.
The WD RE4-GP has a 2TB capacity spread over four platters. It also uses 64MB of cache instead of the 32MB you would find on the 2TB Caviar Green. Western Digital claims that the drive has a mean time between failure (MTBF) of 1.2 million hours — comparable to Intel's enterprise X25-E solid-state drives.
We conducted benchmark tests with a testbed PC running a Western Digital 300GB VelociRaptor internal hard drive. In our large file test, comprising 20GB worth of 3-4GB files, the RE4-GP internal hard drive wrote at 78.86 megabytes per second (MBps), read at 79.5MBps and performed a simultaneous read/write operation at 36.1MBps. Copying 3GB of 1MB files, the hard drive wrote at 50MBps, read at 66.7MBps and performed a simultaneous read/write operation at 38.5MBps. While the RE4-GP isn't as fast as the Velociraptor it is still significantly better than the 2TB WD Caviar Green (WD20EADS).
The RE4-GP uses Western Digital's "GreenPower" collection of technologies — IntelliPower, IntelliSeek and IntelliPark — to cut down on the hard drive's power consumption. IntelliPower varies the drive's spin speed to reduce power consumption when spinning up the drive and during normal operation; as a result, Western Digital doesn't provide a fixed spin speed for the drive.
The other two technologies — IntelliSeek and IntelliPower — affect the heads that the drive uses to write and read from the platters. IntelliSeek calculates the optimum seek speed while IntelliPark moves the drive's recording heads to a secure position when idle. According to WD, these technologies help save energy and reduce noise and vibration.
During our tests, the drive consumed 6.8 Watts when writing, 6.1W when reading, and 7.1W when performing a simultaneous read/write operation. It consumed 4.5W when idle. This is more than the 3.7W quoted by Western Digital and is probably caused by the variable spin speed. Overall, the RE4-GP consumed less power than the enterprise-focussed 1TB RE2 GreenPower drive.
Noise was minimal even during intense operations; we were unable to detect vibration without feeling the underside of the drive. The drive uses Western Digital's Rotary Acceleration Feed Forward (RAFF) technology, which the company says reduces vibration caused by other hard drives close by.
The RE4-GP internal hard drive maintained a temperature range of 33-39 degrees Celsius during testing in an open-air environment, which is slightly higher than the temperatures the 2TB Caviar Green (WD20EADS) registered.
With a formatted capacity of 1863MB, the RE4-GP has a cost per gigabyte of 25.2c. This cost is slightly higher than the 2TB Caviar Green's 20.8c per gigabyte, but is still a reasonable figure given the drive's capacity. A five-year limited RMA (Return Materials Authorisation) warranty is provided by Western Digital.
Overall, the RE4-GP internal hard drive offers a great compromise between performance and low power consumption. Western Digital's energy saving and vibration reduction technologies, combined with a higher cache than WD's 2TB Caviar Green drive and fast throughput speeds, make this drive a great addition to data centres.

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.
