Hitachi recently started shipping a pair of 4 TB hard drives. We can see that they're pretty expensive, but how do they compare to existing 3 TB models in other ways? It's time for a comprehensive overview of today's high-capacity hard drive offerings.
LG's IPS monitors head downmarket with 2D-only IPS4 series launching soon
URL: http://www.engadget.com/2012/04/27/lg-ips4-monitor/
While LCD monitors with in-plane switching technology were once decidedly settled at the high end, LG apparently thinks its time for everyone to have one and is launching its mainstream IPS4 line. Executive VP JJ Lee says the aim is for IPS monitors to become "ubiquitous in every room", bringing better color reproduction, picture quality and wide viewing angles with them. So far we know they're slotting in just below the 3D-capable models shown off at CES, but there's nothing mentioned in the press release (included after the break along with another pic) about prices, sizes, specs or model numbers. If you're in the market however, expect to find out more soon since they will roll out to Asia first in May, followed by Europe and North America in "the coming weeks".

Lâmpada que dura 20 anos e custa US$ 60 chega às lojas nos EUA
Uma lâmpada que dura 20 anos e custa US$ 60 (cerca de R$ 110) começou a ser vendida nos Estados Unidos nesta semana. O produto, fabricado pela multinacional Philips, substituiu os tradicionais filamentos por diodos emissores de luz (LED, em inglês). A tecnologia LED aumenta a vida útil das lâmpadas, mas também encarece a mercadoria. Para tentar contornar o problema que pesa nos bolsos dos consumidores, a empresa está oferecendo descontos em algumas lojas. Com eles, a lâmpada especial pode custar até US$ 20 (cerca de R$ 35).

The Intel Ivy Bridge (Core i7 3770K) Review
URL: http://www.anandtech.com/show/5771/the-intel-ivy-bridge-core-i7-3770k-review
The times, they are changing. In fact, the times have already changed, we're just waiting for the results. I remember the first time Intel brought me into a hotel room to show me their answer to AMD's Athlon 64 FX—the Pentium 4 Extreme Edition. Back then the desktop race was hotly contested. Pushing the absolute limits of what could be done without a concern for power consumption was the name of the game. In the mid-2000s, the notebook started to take over. Just like the famous day when Apple announced that it was no longer a manufacturer of personal computers but a manufacturer of mobile devices, Intel came to a similar realization years prior when these slides were first shown at an IDF in 2005:
IDF 2005
IDF 2005
Intel is preparing for another major transition, similar to the one it brought to light seven years ago. The move will once again be motivated by mobility, and the transition will be away from the giant CPUs that currently power high-end desktops and notebooks to lower power, more integrated SoCs that find their way into tablets and smartphones. Intel won't leave the high-end market behind, but the trend towards mobility didn't stop with notebooks.
The fact of the matter is that everything Charlie has said on the big H is correct. Haswell will be a significant step forward in graphics performance over Ivy Bridge, and will likely mark Intel's biggest generational leap in GPU technology of all time. Internally Haswell is viewed as the solution to the ARM problem. Build a chip that can deliver extremely low idle power, to the point where you can't tell the difference between an ARM tablet running in standby and one with a Haswell inside. At the same time, give it the performance we've come to expect from Intel. Haswell is the future, and this is the bridge to take us there.
In our Ivy Bridge preview I applauded Intel for executing so well over the past few years. By limiting major architectural shifts to known process technologies, and keeping design simple when transitioning to a new manufacturing process, Intel took what once was a five year design cycle for microprocessor architectures and condensed it into two. Sure the nature of the changes every 2 years was simpler than what we used to see every 5, but like most things in life—smaller but frequent progress often works better than putting big changes off for a long time.
It's Intel's tick-tock philosophy that kept it from having a Bulldozer, and the lack of such structure that left AMD in the situation it is today (on the CPU side at least). Ironically what we saw happen between AMD and Intel over the past ten years is really just a matter of the same mistake being made by both companies, just at different times. Intel's complacency and lack of an aggressive execution model led to AMD's ability to outshine it in the late K7/K8 days. AMD's similar lack of an execution model and executive complacency allowed the tides to turn once more.
Ivy Bridge is a tick+, as we've already established. Intel took a design risk and went for greater performance all while transitioning to the most significant process technology it has ever seen. The end result is a reasonable increase in CPU performance (for a tick), a big step in GPU performance, and a decrease in power consumption.
Today is the day that Ivy Bridge gets official. Its name truly embodies its purpose. While Sandy Bridge was a bridge to a new architecture, Ivy connects a different set of things. It's a bridge to 22nm, warming the seat before Haswell arrives. It's a bridge to a new world of notebooks that are significantly thinner and more power efficient than what we have today. It's a means to the next chapter in the evolution of the PC.
Let's get to it.

Intel's SSD 910: Finally a PCIe SSD from Intel
URL: http://www.anandtech.com/show/5743/intels-ssd-910-400800gb-mlchet-pcie-shipping-in-1h-2012
Solid state storage has quickly been able to saturate the SATA interface just as quickly as new standards are introduced. The first generation of well-built MLC SSDs quickly bumped into the limits of 3Gbps SATA, as did the first generation of 6Gbps MLC SSDs. With hard drives no where near running out of headroom on a 6Gbps interface, it's clear that SSDs need to transition to an interface that can offer significantly higher bandwidth.
The obvious choice is PCI Express. A single PCIe 2.0 lane is good for 500MB/s of data upstream and downstream, for an aggregate of 1GB/s. Build a PCIe 2.0 x16 SSD and you're talking 8GB/s in either direction. The first PCIe 3.0 chipsets have already started shipping and they'll offer even higher bandwidth per lane (~1GB/s per lane, per direction).
Today Intel is announcing its first PCIe based solid state solution: the Intel SSD 910. Read on for our analysis of the announcement!
Intel Z77 Panther Point Chipset and Motherboard Preview – ASRock, ASUS, Gigabyte, MSI, ECS and Biostar
Well, today is a day that everyone was expecting, but perhaps not the most exciting day of the month. Today, Intel officially releases the spate of 7-series chipsets for their 3rd generation Core microarchitecture processors (read—Ivy Bridge), despite the actual release of the processors being another three weeks away. This means that today we can actually look at, test, or purchase the range of motherboards that natively support Ivy Bridge. However, we can’t officially publish all the benchmarks for these products using Ivy Bridge until that date three weeks away (to be honest, we are still testing!). So today we are going to have a good in depth look into the Z77 chipset itself, and the review products we have received to let you know what we think looks good. All these boards today will be fully reviewed, warts and all, with Ivy Bridge, as close to official release as possible.
The boards today are from ASRock, ASUS, Gigabyte, MSI, ECS and Biostar. All these boards will natively support Sandy Bridge processors, and be fully upgradeable to Ivy Bridge silicon when the processors are released. Read on for the preview.

Intel's next-generation processor may be the worst-kept secret in the industry right now. Intel has disclosed quite a bit about Ivy Bridge, and other details have already leaked onto the web, including specifications, benchmark results, and Intel's own marketing materials—yet I've been asked to refrain from mentioning her by name. Instead, she's to be referred to only as Intel's "3rd generation Core processor." And she's not ready yet.
Intel has confirmed that Ivy Bridge's arrival has been delayed to iron out kinks in the 22-nm fabrication process used to make the chip. We may not see notebooks featuring Intel's new hotness until June. Desktop versions of the CPU should be available before ...

Google Glasses Face Serious Hurdles, Augmented-Reality Experts Say
Is Project Glass feasible? Photo: Google
When Google officially unveiled Project Glass — the company's bid to develop Terminator-style augmented-reality glasses — we saw a provocative glimpse of the future. The video Google released yesterday showed us the point of view of someone wearing the glasses, with icons, maps and other graphical overlays appearing over the user's complete field of vision.
Accompanying photos, meanwhile, showed us how the new glasses might look — but the glasses weren't really glasses. Instead, we saw a system that lacked full lenses, and included just a small, rectangular pieces of glass hovering over the wearer's right eye.
If anything, the system in the photos looks similar to what Recon does with its head-up-display snowboarding goggles: Data overlays don't consume one's entire field of vision. Rather, small bits of data appear only in one's peripheral vision.
”In one simple fake video, Google has created a level of over-hype and over-expectation that their hardware cannot possibly live up to.” — Blair MacIntyre, Georgia Tech
So where is Google really going with Project Glass? The hardware that appears in the photos doesn't appear capable of delivering the augmented-reality experience we see in the video. Is Google working on two different delivery systems? Or is the company going with a Recon-style approach, but released a video that over-reaches?
We asked Google for specifics, and were told in an e-mail, “We aren’t prepared to put additional information on the record at this time.”
However, according to Pranav Mistry, an MIT Media Lab researcher and one of the inventors of the SixthSense wearable computing system, “The small screen seen in the photos cannot give the experience the video is showing.”
Blair MacIntyre, director of the Augmented Environments Lab at Georgia Tech, concurs: “You could not do AR with a display like this. The small field of view, and placement off to the side, would result in an experience where the content is rarely on the display and hard to discover and interact with. But it’s a fine size and structure for a small head-up display.”
Mistry does point out that the Project Glass demo is a concept video. But MacIntyre believes Google may have set the bar too high for itself. “In one simple fake video,” MacIntyre told Wired, “Google has created a level of over-hype and over-expectation that their hardware cannot possibly live up to.”
“Some of what I find a little annoying about the video is that they staged all these things such that as when these notifications come to the middle of the screen, the person is looking at the thing it’s referring too,” MacIntyre said. “Is it augmented realty, or is it location-based notifications? It’s going to generate ideas in people and expectations that just might not match.”
Even if Google is able to deliver the goods, says Mistry, we won’t see the glasses on the market for at least two years. Most of this has to do with limitations in current mobile display technology. “Current HUDs utilize a fixed lens distance of two feet,” he says. “For true augmented reality, the display would have to dynamically focus, which would require additional hardware on the glasses to read your eye.”
MacIntyre brings up another issue. He’s found that in his own Georgia Tech research, it’s difficult to create a transparent display that renders viewable overlays both indoors and outdoors. “The brightness difference between inside your bright office and outside on a bright day is multiple orders of magnitude,” he says.
In other words, a display bearing overlaid graphics that performs well indoors would be washed out when the user encounters the brightness of the outside world. Because of such huge differences in ambient lighting, MacIntyre says creating a display that can handle multiple environments will be difficult. “You wouldn’t be able to accomplish it by just changing the brightness,” he says.
Google’s public posting on Project Glass couches the technology in incredibly vague terms: “So we took a few design photos to show what this technology could look like and created a video to demonstrate what it might enable you to do.” Nonetheless, if Google is unable to deliver on most of what the video shows, all the research in the world won’t stop consumers uttering the worst word in the technology world: vaporware.

Why Samsung Makes Retina Displays — But Not for Its Own Tablets
URL: http://www.wired.com/gadgetlab/2012/04/samsung-tablet-ipad-retina-display/
Is Samsung in the weeds with its display technology? Photo: Ariel Zambelich/Wired 
If you haven’t yet laid eyes on the new iPad’s screen, you must. “Sharp” doesn’t begin to describe Apple’s upgrade in display quality. But here’s the kicker: Samsung, a company firmly aligned with Android and one of Apple’s largest competitors in the mobile space, is manufacturing the new iPad’s flagship feature.
So, naturally, questions arise: Why are we seeing Retina displays in iPads but not in Samsung’s own Galaxy-branded tablets? Why would Samsung allow itself to be trumped by a mere customer?
A Brief History
The component supply industry is backwards, convoluted and damn near impenetrable. Like some twisted web of New Jersey mafioso, competing companies will cut opponents’ throats on the very same day they cut each other deals.
Example: While Samsung pumps out tens of thousands of high-end LCD panels for Apple, the two companies remain embroiled in longstanding intellectual property litigation, with Apple accusing Samsung of blatantly ripping off the iOS user interface, as well as Apple’s iconic product designs.
Samsung isn’t just “Samsung,” though. It’s a massive, multi-national conglomerate made up of more than 30 independent businesses, covering areas as disparate as life insurance and petrochemical engineering. One such free agent is Samsung Mobile Display. Founded in 2009, this company takes the years of R&D done by Samsung Electronics and Samsung SDI in AMOLED technology, and uses it to tuck nicely into products such as televisions, tablets and mobile phones.
So while Samsung Electronics Company LTD gets its pants sued off, Samsung Mobile Display wheels and deals with Apple at the very same time. And, of course, while all this is happening, both companies compete fiercely to sell mobile phones and tablets as quickly as possible.
Samsung isn’t the only company that manufactures displays for direct hardware competitors. LG and Sony — both notable players in the Android phone and tablet space — do it too. To put it simply: It’s complicated.
AMOLED’s Roots Run Deep
As it stands, Samsung champions a display technology for its own mobile products that’s currently of no appeal to Apple. Dubbed AMOLED (shorthand for active-matrix organic light-emitting diode), Samsung has deployed this display tech in millions of mobile phones — most notably, the Galaxy SII, the company’s flagship Android device of 2011. The Galaxy Tab 7.7 also touts a Super AMOLED display as one of its most noteworthy features. (The “Super” variety of AMOLED integrates touch sensors directly in the surface glass of the screen, increasing brightness and reducing power consumption.)
Indeed, Samsung has a lot riding on AMOLED technology. “They’ve invested a considerable amount of money into OLED development and products in that industry,” Vinita Jakhanwal, an analyst with IHS iSuppli told Wired. “Tens of billions of dollars in investment over the past decade.”
In a sense, Samsung has a notable edge over competitors in the display space. Currently, Samsung Mobile Display is still the only manufacturer that can mass-produce Super AMOLED displays, says NPD DisplaySearch analyst Paul Semenza. And the company is using its advantage by pushing it out to Samsung-branded phones. “The Galaxy S phones have been quite successful by highlighting the AMOLED display,” Semenza says.
Part of the success ties to AMOLED advantages over LCD. For one, AMOLED displays consume relatively little power — a nice benefit of a design that requires no battery-draining backlights. Relative to LCDs, AMOLED displays also offer higher contrast ratios and color saturation, with reds, greens and blues looking brighter and more spectacular. And while AMOLED currently costs more to produce than LCD, the price will decrease over time as Samsung scales its display manufacturing capabilities.
In order to focus on AMOLED, Samsung recently spun off its unprofitable LCD business. “Samsung essentially owns the supply on AMOLED screens,” NPD DisplaySearch analyst Richard Shim told Wired. “And they're going to give it all to Samsung Mobile Group.”
Though Apple and Samsung compete in one arena, they remain unlikely bedfellows in others. Photo: Jon Snyder/Wired
Tradeoffs
Of course, in looking at any competing technologies, there will always be tradeoffs, and AMOLED doesn’t trump LCD in every department.
First off, Samsung’s AMOLED technology can’t currently deliver the amazing 2048×1536 screen resolution of the new iPad, which packs more than 3 million pixels inside a 9.7-inch display. What’s more, some tests have shown that the organic materials used in OLED displays have a shorter brightness lifespan than those used in LCDs (depending on the type of device). So after five years or so, your handset may be half as bright as it used to be (though, to be fair, this is mostly an issue in TVs rather than phones, which we tend to replace every two to three years).
Technical limitations notwithstanding, Samsung may be compelled to stick with AMOLED displays simply for a dramatic point of differentiation in the tablet space. In short, the Retina display may be awesome, but at least a tablet with an AMOLED display is different.
“Most tablets have similar types of functions and features,” Jakhanwal said. And when every tablet looks and acts like every other one, customers have no reason to choose one over another. “So the [original equipment manufacturers] are looking to differentiate their products,” Jakhanwal said. Tablets are basically all display, so adopting a novel screen technology is perhaps the best starting point for differentiation.
Consumers Don’t Want It — Until Apple Tells Them They Do
Here’s the problem with Apple: The company is intent on solving problems we never knew we had. The tablet form-factor was laughed at when Steve Jobs first introduced it. Tens of millions in iPad sales later, and the naysayers are eating crow (not to mention trying to make successful tablets of their own).
That’s the case with the new iPad and its fancy-pants display. “Consumers aren't necessarily asking for higher resolution,” says Richard Shim. “But this is sort of Apple's M.O — the idea that, ‘You don't know what you want because we haven't told you yet.’”
So now the onus is on Samsung to convince us that while we should care about display tech, it’s brightness and color — two areas in which AMOLED excels — that we really need to worry about.
Will Samsung stay the course and make AMOLED the future in all of its devices? Or will it cave and follow Apple’s lead yet again? We don’t know for sure, but it’s nice to imagine Samsung will try and think different (so to speak) in order to outsmart the competition.
