Seagate 8TB Archive HDD

We create more data every time we snap a picture with our phone, record a video or post something to a social media website. The budding Internet of Things (IoT) means that our thermostats, vehicles and toasters (conceivably) only add to this unending stream of data. The Internet reaches to the far flung corners of the globe and the number of users streaming data, seemingly just into the nether, continues to expand every day.

The only problem is that the data isn't actually disappearing into the nether. We expect to be able to retrieve a family picture in mere milliseconds from Facebook even if we uploaded it (and forgot about it) five years ago. We increasingly (and blindly) trust that our social media services will safely store our data and memories, well, forever.

The picture from your latest snap has to land somewhere, and that "somewhere" is a server that churns away day and night. This influx of data creates a tremendous challenge at the other end of the pipe, and datacenter operators are tasked with keeping this exponentially increasing burden of data under safe keeping; but the key is to do it in a cost-effective manner.

HDD vendors have responded to the need for more storage with clever engineering that increases the amount of storage they can provide per device, as well as per dollar. The newest innovation comes in the form of SMR (Shingled Magnetic Recording), which overlays data tracks to increase the amount of available storage capacity.

The Seagate SMR datacenter offering lowers cost to an unheard-of three cents per gigabyte of storage (and that is at retail pricing). This low cost has made the drives increasingly popular with consumers for bulk data storage, which is a use-case the drive excels at.


However, SMR is not without its tradeoffs. For those who aren't familiar with the limitations of SMR technology it can become a frustrating experience. Never fear, we've got it all figured out. Come along as we explore all things SMR in our Seagate 8TB Archive HDD Review at Tom's IT Pro.

Space station getting inflatable room, a cosmic 1st

CAPE CANAVERAL, Fla. — Forget blowup air mattresses. Space station astronauts are getting their first inflatable room.

It's a technology demo meant to pave the way for moon bases and Mars expeditions, as well as orbiting outposts catering to scientists and tourists in just a few more years. Bigelow Aerospace is behind the experiment, which will get a ride to the International Space Station with another private space company.

An unmanned SpaceX Falcon rocket is set to launch late Friday afternoon, carrying a capsule full of supplies with the pioneering pod in its trunk. It will be SpaceX's first station delivery since a launch accident halted shipments last June.

Once attached to the station, the soft-sided Bigelow compartment will be inflated to the size of a small bedroom. The Bigelow Expandable Activity Module, BEAM for short, will stay there for two years — with astronauts occasionally ducking in. It will be the first time an astronaut steps inside an expandable habitat structure in space.

"It's not just historic for our company, which obviously is the case, but I think it's historic for the architecture," said Robert Bigelow, founder and president of Bigelow Aerospace and owner of Budget Suites of America.

As a precursor to larger systems, Bigelow said BEAM could "change the entire dynamic for human habitation" in space. He hopes to have a pair of private space stations ready for launch by 2020.

In the meantime, companies— even countries — are clamoring to put their own experiments inside the empty BEAM, Bigelow said in an interview with The Associated Press on Thursday. If everything goes well, that next commercial step could happen in perhaps six months, he said.

The North Las Vegas-based company won't divulge the material used for BEAM's outer layers — or even how many layers — just that the layers are spread out to absorb and break up any penetrating bits of space junk. Back when NASA was working on the technology in the 1990s, a combination of Nextel, Kevlar, foam and other fabric formed the multilayer shield.

NASA called its project TransHab, for Transit Habitat. It never flew to space, despite elaborate blueprints and ground mock-ups. Designers envisioned an inflatable, four-level compartment, complete with dining, sleeping and exercising areas for station crews.

Congress canceled TransHab in 2000 and Bigelow Aerospace bought the patent from NASA. The company launched a pair of expandable spacecraft a decade ago from Russia as an experiment. Called Genesis I and II, they're still orbiting.

NASA, meanwhile, paid Bigelow Aerospace $17.8 million for the upcoming test flight, making the BEAM the most affordable module ever launched to the space station, said Michael Gold, director of operations and business growth for Bigelow Aerospace.

Expandable habitats like BEAM, officials noted, need to be just as strong — or stronger — than the standard metal cylinders that make up the current space station. BEAM has proven to be equal or better against space debris than metal, said NASA project manager Rajib Dasgupta.

Bigelow goes as far as to say: "The aluminum cans are antiquated."

Beyond low-Earth orbit, radiation poses increased health risks to crews living inside aluminum walls. So inflatable spacecraft, he said, are cheaper, bigger, safer and, potentially, longer lasting.

Bigelow said BEAM is nothing like a balloon — "it's not going to go bang" — or even a football. Think steel belts in a car tire. "It's pretty novel."
