We plugged the My Book into an Apple Time Capsule 802.11n router to which we also connected the Ethernet port of a MacBook Pro to the Time Capsule, ensuring a Gigabit pathway from My Book to router to Mac.

The Time Capsule contains a 500GB 7200rpm Enterprise-class Seagate drive. That's half the capacity of the drive in the My Book, but it pumped out consistently more heat during testing - though it's worth bearing in mind that the TC's AC adaptor is built in; the My Book's is separate. That said, the Apple unit is more tightly sealed, so there was little to choose between them when it came to noise, with not much of it.
First, we copied an 8GB file from MacBook Pro to the two drives, between the drives and then back to the laptop. The My Book's drive is nominally rated at 7200rpm, but you can see from the chart that we got better file copy performance from the WD than from the Apple unit.
We should point out that we made sure the Time Capsule's drive was spinning before timing the copy actions. The Time Capsule's firmware spins down the HDD after a period of inactivity, partly to conserve power, but mostly to help keep the heat down. Add in the TC's drive spin-up time, an the My Book's lead is enhanced. And it was always ready to begin copying files immediately.

Still, it's not quite the equivalent of hanging a USB drive off a single machine, and we've included appropriate figures to show you. Maybe with a fast desktop drive, you'd get close to USB speeds, but not with your average laptop. And certainly not if you're connecting your computer to the router over Wi-Fi or 10/100Mb/s Ethernet.

Looks nice on a desk - but better on a bookshelf
Yes any dvice without wires looks nice on a desktop..
Im a QNAPer and wont be converted.
WD's perf figures
Tom's hardware seem to have missed a trick in not conducting their own full wired Ethernet perf tests, but the (WD supplied) file transfer and IOzone perf charts look pretty good:

Re: Significant Improvements Made
Scott, if you're going post this exact same sales blurb in several hardware review sites then please try and tailor your posts to address the gripes users have had with this particular piece of hardware rather than reiterate the basic sales pitch.
I'm particularly referring to the rate-limited network interface which prevents people from getting the full advertised network speed from the hardware after they've purchased it. This is something that burnt quite a few users after they purchased the previous version of the My Book World.
If this is fixed in the new version then you've got yourself a convert, otherwise this is just the same hardware with a bigger drive and updated software, which is something users can upgrade themselves using the right linux tools and an el cheapo spare drive.
Availability
@Sentry23, search for WDH1NC10000, there's not much out there and the only place I found it in said "Available in about 28 days"
@Scott Rader
Hey Scott, are you a WD guy?
I assume you've kept with ARM chip. What does it clock at?
How much RAM is there?
What kernel are you using?
