USB 3.0 Will Deliver 100 Watts Of Power In 2012

USB 2.0 brought us 480Mb/s transfer speeds and 2.5 watts of power over the cable. This required either a second USB cable for additional power or a plug in power adapter. Either way, it was a hassle to power even moderately speedy external hard drives.

USB 3.0 brought a massive speed increase to 5Gb/s transfer speeds; however, power only received a relatively small bump to 4.5 watts of power over the cable (900mA at 5V). While the bump in power can now more easily power most external hard drives, power hungry high speed mechanical and solid state hard drives that are able to fully take advantage of the speed increases of USB 3.0 will still require additional power.

In an interesting move by the USB 3.0 Promoters Group, a new USB 3 specification will provide up to 100 watts of power at varying voltages to external devices. This great increase in power would allow users to power external USB monitors without a separate power adapter, RAID enclosures, desk lamps, USB grills (okay, maybe not), and other multiple hard drive external enclosures like the Drobo boxes.

While the new specification is due out next year (2012), it will be some time before hardware (specifically power supplies) catches up to the specification’s maximum power draw. Do you think the move to deliver more power through the USB 3 cable is a good one, or will the increased complexity of delivering 100 watts over the same cable delivering data outweigh the convenience of only needing a single cable?

Can Plextor compete with Drobo?

There once was a time, when dinosaurs like Compaq ruled the earth, when there was only one choice for the true enthusiast when buying a CD burner.  Plextor was by far the most reliable choice in a time when CDs were more sensitive to external vibrations than a fine souffle. Things have changed a great deal since then and the looks you get when you ask how many sheep your burner has can be quite amusing.   This has left Plextor looking for alternative revenue sources and the area they have chosen is NAS devices.  The new Plextor PX-NAS4 has impressive stats but it is competing against heavy hitters like Drobo.  Think Computer tries out this ~$400 NAS device and contrasts its features and controls with similarly priced competitors offerings in their latest storage review.

"Plextor introduced the PX-NAS4 quad-bay network attached storage device late last year to augment its PX-NAS2 dual-bay device and break into a market with larger storage needs. The dual gigabit Ethernet PX-NAS4 can house up to 8 TB of storage in several RAID configurations and sports volume encryption and low power consumption among other standard enterprise and business features. ThinkComputers takes a look, and finds that while the PX-NAS4 provides the basic features, it leaves something to be desired for users with more. Read on for the review."
