Seagate Releases 6TB Hard Drive Sans Helium 147

Lucas123 (935744) writes "Seagate has released what it said is the industry's fastest hard drive with up to a 6TB capacity, matching one released by WD last year. WD's 6TB Ultrastar He6 was hermetically sealed with helium inside, something the company said was critical to reducing friction for additional platters, while also increasing power savings and reliability. Seagate, however, said it doesn't yet need to rely on Helium to achieve the 50% increase in capacity over its last 4TB drive. The company used the same perpendicular magnetic recording technology that it has on previous models, but it was able to increase areal density from 831 bits per square inch to 1,000. The new drive also comes in 2TB, 4TB and 5TB capacities and with either 12Gbps SAS or 6Gbps SATA connectivity. The six-platter, enterprise-class drive is rated to sustain about 550TB of writes per year — 10X that of a typical desktop drive."

Statistically speaking even if your body can live forever, some kind of accident will almost certainly kill you in that ten thousand year timeframe.

Wouldn't people get more risk-averse and change the probabilities? You've driven behind 70-year-old-guys. Now imagine 7000-year-old-guy is driving the car in front of you!


Japanese Firm Proposes Microwave-Linked Solar Plant On the Moon 330

littlesparkvt writes "Harnessing the sun's power is nothing new on Earth, but if a Japanese company has its way, it will build a solar strip across the 11,000 mile Lunar equator that could supply our world with clean and unlimited solar energy for generations." Some of the company's other projects look just as ambitious.

Most of the Internet is built this way already. The Internet backbone is mostly idle and under-utilized. About 80% of the fiber that was installed for the backbone has gone unused as technology keeps pushing data transfers faster and faster.

Let's take round numbers - 100 fiber pairs between a pair of major cities, with 80 of them unused, and (say) 1Tbit/s on the other 20 pairs. That's 20Tbit/s of backbone capacity, and you might think of it as 80Tbit/s "unused". However, to bring those fibers into use, you need to sink the capital costs for the routers, optics for the 10 or 100Gbit/s ports, and the DWDM equipment. That's not a trivial cost, and people will need a business case for turning up new capacity.

It's a lot easier to upgrade the core than the edge, but the core router ports certainly aren't sitting there at some low utilization all the time.

Here's what the internet has to say ( )

Yep. 100% sure. I've even researched how so many people can believe this is an actual quote when it isn't (which is a strange phenomenon). I'm also a huge Simpsons geek.

The actual quote is: Wiggum: Well that's some good work, Lou. You'll make sergeant for this.

But almost universally people say and believe it to be "That's some (mighty) fine detective work, Lou"
