Western Digital releases monster 4TB hard drive

My Book Studio Edition II uses 30% less power than other WD drives

Western Digital Corp. today released its biggest consumer external hard-disk drive targeted at Mac users with a whopping 4TB of capacity.

The drive's $650 price tag may turn some off, but if you need space to fit 1,540 DVD movies, 800,000 digital photos or one million MP3 music files, then this may be the drive you.

The My Book Studio Edition II drive comes in 1TB, 2TB and 4TB capacities and is designed with WD's GreenPower Technology, so the system uses about 30% less energy than standard WD drive systems and runs quietly because it doesn't need a fan.

The drive comes with a four ports, ultra-fast eSATA and FireWire 800, and FireWire 400 and USB 2.0, along with the accompanying cables.

It is compatible with Apple's Time Machine and includes software and instructions for reformatting to Windows operating systems. The system supports Mac OS X 10.4.10+, 10.5.2+ Windows 2000/XP/Vista: The 4TB version works with Windows Vista only because Windows XP does not support hard drives with capacities above 2TB.

The new My Book Studio Edition II two internal drives can be configured for RAID 0, which affords users the full 4 TB of capacity, or RAID 1, which mirrors the two drives to protect data in case of a drive failure but reduces storage capacity by half.

The new drive comes with a 5-year limited warranty.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
