The 15-petabyte network behind the Cern atom smasher

, , ,

Enough information to fill multiple CDs every second is flowing across the world on a network one thousand times faster than home broadband.

Terabytes of data are streaming through dedicated fibre optic links between laboratories and universities globally in preparation for the world's largest particle accelerator, the Large Hadron Collider (LHC), being switched on in August at Cern in Geneva, Switzerland.

The Large Hadron Collider Computing Grid (LCG), a super high bandwidth network, will channel about 15 petabytes - 15 million gigabytes - of data from the LHC to about 5,000 scientists in 500 institutions every year for at least 10 years.

Seagate's Latest Desktop HDD Has 1.5TB Capacity

, , , ...

Seagate announced three new consumer-level hard drives recently, which it claims are the "industry's first 1.5-terabyte desktop and half-terabyte notebook hard drives." The company claims that it is able to greatly increase the areal density of its drive substrates by utilizing perpendicular magnetic recording (PMR) technology. Wikipedia states that PMR is "capable of delivering more than triple the storage density of traditional longitudinal recording."

Seagate's latest desktop-class hard drive, the Barracuda 7200.11, will be available in a 1.5TB capacity starting in August. The 3.5-inch drive is made up of four 375GB platters and has a 7,200-rpm rotational speed. It has a 3Gb/second SATA interface, or 1.5Gb/second using Native Command Queuing (NCQ). Seagate also claims that the new 1.5TB drive supports a sustained data rate of up to 120MB/second.
