For those without a USB 3.0-capable motherboard, an NEC PCIe USB 3.0 card is supplied with the My Book if you buy the full kit. Installation is straightforward, but does require additional drivers from the included CD, as even Windows 7 doesn't ship with USB 3.0 support. The My Book 3.0 feels light, yet solid and sturdy. It features a single LED status light, but lacks the LED usage meter present on other products in the My Book line.

Longer bars are better
In general, the drive runs cool and quiet which suggests, even though WD does not let on, that this NTFS-formatted model utilises its line of Caviar Green hard disks. I would have no problems running this model on mu desk in close vicinity to the working area. A Kensington security slot is also included for those worried about envious co-workers lusting over your new USB 3.0 toy. Such jealousy is inevitable; just look at the performance figures.
To give you an idea of just how fast this is I’ve compared it to the next fastest drive Reg Hardware has reviewed, Iocell’s NetDisk 351UNE which also uses Western Digital Caviar Green drives. The NetDisk, however, uses eSata but it is still the closest parallel, until Reg Hardware gets some more SuperSpeed USB 3.0 drives to test.
Clearly, USB 3.0 has a major advantage over USB 2.0, offering speed increases of approximately 100 per cent in random I/O operations and 250 per cent in sequential I/O operations. It is also clear that the limiting factor is now the internal bus of the hard disk used, rather than the connecting interface.
USB backward compatible, but with obvious performance penalties
With the release of the My Book 3.0, Western Digital has shown that external hard drives no longer need lag behind internal disks, while still maintaining compatibility with legacy systems. USB 3.0 is expected to enter mainstream usage when Intel adopts the standard in 2011, making these technological advances the norm among consumer applications.
If eSata is not for you, or you are one of the few already equipped with a USB 3.0 capable computer and don’t feel like waiting for all the other USB 3.0 products announced at CES, then go and pick up the My Book 3.0, as there’s not much else out there. Go on, put those ports to work. ®

Review incomplete -- CPU utilization
The transfer figures look nice, but what was the CPU utilization? I have read elsewhere that USB 3 will use substantially more CPU than eSATA, and was hoping for a comparitive set of numbers....
Can Anyone Explain
How a SATA drive connected via a USB3 HBA could POSSIBLY be faster than that same drive connected natively over eSATA?
Second vote for FAIL
The main problem for USB2 is indeed the CPU killing nature of it. Any self respecting geek is already extremely well aware of that.
To do one of the first reviews of an actual in the flesh device replete with performance graphs with not even a passing mention of the CPU impact smacks of schoolboy ignorance at best, despite what some knobhead AC might think
Intel wins either way
either licensing from LightPeak, or extra CPU cores just for USB!
Need a WIN! sign
@ AC 15:17 - totally disagree
The charts show that esata was nearly as fast except for reads. CPU utilization of USB 3.0 is completely relevant as USB 2.0 alone can drive some major CPU time.
However, I still believe that USB 3.0 is a good path forward compared to that LightPeak garbage Intel was trying to propagate in its place. (Since when has fiber optic ever been resilient or cheap?)
