Seagate goes USB 3.0 for portable drive

Seagate has announced a portable external drive featuring USB 3.0 connectivity.

Seagate's BlackArmor PS110 is among the first external hard drives to feature a USB 3.0 interface.

Although the raw speed of USB 3.0 is nominally ten times that of USB 2.0 (4.8Gbps vs 480Mbps), the actual throughput of Seagate's portable drive using the new interface is three times that of USB 2.0.

Not as impressive a number as ten times, but nevertheless a welcome improvement. Seagate officials point out that it means a 25GB HD movie can be transferred in four minutes, compared with 14 minutes using USB 2.0.

Sustained data transfer rates of 100MBps are said to be possible.

"The growing presence of large multimedia files in the home means that connectivity and speed is a top concern for a satisfactory experience," said Dave Mosley, Seagate executive vice president, sales, marketing and product line management.

"The delivery of USB 3.0 further underscores our commitment to giving people an efficient way to store, access and share their digital creations," he added.

Since a USB 3.0 drive is of little benefit if the computer it's used with only has USB 2.0 ports (it works, but there's no speed improvement), Seagate is bundling the drive with a USB ExpressCard adaptor.

The package also includes Acronis backup software and SafetyDrill+ for bare metal recovery for Windows XP. Vista or 7.

Updated: The BlackArmor PS 110 USB 3.0 Performance kit costs $US179.99. Australian pricing and availability has yet to be announced.

Now’s the Time for 400G Migration

The optical fibre community is anxiously awaiting the benefits that 400G capacity per wavelength will bring to existing and future fibre optic networks.

Nearly every business wants to leverage the latest in digital offerings to remain competitive in their respective markets and to provide support for fast and ever-increasing demands for data capacity. 400G is the answer.

Initial challenges are associated with supporting such project and upgrades to fulfil the promise of higher-capacity transport.

The foundation of optical networking infrastructure includes coherent optical transceivers and digital signal processing (DSP), mux/demux, ROADM, and optical amplifiers, all of which must be able to support 400G capacity.

With today’s proprietary power-hungry and high cost transceivers and DSP, how is migration to 400G networks going to be a viable option?

PacketLight's next-generation standardised solutions may be the answer. Click below to read the full article.
