LaCie pumps more data down USB 3 link

Dual drive uses USB 3 better

Combat fraud and increase customer satisfaction

LaCie is prepping dual drive RAIDed storage box delivering up to 275MB/sec across its USB 3.0 link.

The product is the 2Big USB 3.0, with two hard drives, a maximum capacity of 4TB - ergo 2 X 2TB 3.5-inch hard SATA drives - and either RAID 0 or RAID 1 configurations. It uses a dual USB 3.0 SATA and RAID bridge controller from Symwave. The 275MB/sec speed is for burst read transfers of uncompressed video.

LaCie says its fast new box "reaches the highest throughput ever achieved in a USB 3.0 external storage product" and it is faster than the Buffalo HD-HXU3 single drive external storage box and its up to 130MB/sec figure. The LaCie claims indicate that the reason for slow USB 3.0 link performance in single drive products is largely down to the SATA drive's inability to pump data fast enough through the link, or, indeed, receive it. Having two drives streaming off data pushes more data down the USB 3 pipe.

We don't know the intermediate capacity points for LaCie's USB 3.0 2Big and neither do we know the prices yet, but it will come with both PC and Mac backup software. LaCie and Symway will demo the box at CES 2010 in Las Vegas in January.

LaCie says it "will launch a full range of [USB 3.0] products in the coming months." Good-oh. ®
