Micron Solid State Drive C400 SED Featuring Self Encryption

  • Micron Solid-State Drive C400 SED Featuring Self Encryption

In a press release made on the 20th September 2011, Micron announced that they have now increased user security with the new Solid-State Drive Featuring Self Encryption for Laptops and Desktops. Below is the press release, followed by a review of the C400 SED :-


Micron Bolsters User Security With New Solid-State Drive Featuring Self Encryption for Laptops and Desktops

C400 SED Offers Extreme Stability and Robust Protection

Micron Solid-State Drive C400 SED Featuring Self Encryption picture 1
BOISE, Idaho, Sept. 20, 2011 (GLOBE NEWSWIRE) -- Micron Technology, Inc. (Nasdaq:MU), today introduced a new version of its popular RealSSD™ C400, featuring self encryption for unmatched data security. The C400 SED (Self-Encrypting Drive) is based on the Trusted Computing Group (TCG) Opal specifications and provides a hardware-based answer for the increasing wave of data breaches that continue to impact computer users and enterprises worldwide.

Security breaches caused by malicious attacks are on the rise, according to the recent Verizon Data Breach Investigations Report. While its notable that the increase in small-scale external attacks doesnt rely on highly sophisticated approaches, encryption is widely credited as the first choice for the most affordable security solution for deterring such intrusions.

"Self-encrypting drives represent the future of data protection," said Dr. Joerg Borchert, 2011 president and chairman of the nonprofit Trusted Computing Group. "Hardware encryption provides the strongest security and best performance, and solid-state technology like Microns will provide even quicker data access."

The C400 SEDs encryption capabilities are delivered through a hardware-based, AES-256-bit encryption engine and advanced security firmware. Microns firmware is designed to comply with the TCG Opal specification. TCG Opal is an open industry standard that provides a verifiable path for companies who need to prove theyre compliant with tough data security regulations when devices or drives are lost or stolen.

Like all hardware-encryption, the drive works in conjunction with an encryption management system. Microns C400 SED solution was built in partnership with leading encryption management provider Wave Systems (Nasdaq:WAVX). Waves EMBASSY® management software provides policy-based access controls, comprehensive reporting, directory services integration and end-user access recovery that allows IT to cost-effectively implement and administer endpoint encryption. Importantly, Waves management software gives IT confidence that data is protected in the event that a computer—or the drive itself—is lost or stolen.

"Micron is a true innovator in the field of flash-based storage devices and we applaud their decision to incorporate Opal-based encryption on their new C400 drives," said Steven Sprague, CEO and President of Wave Systems. "By incorporating self-encryption in the C400 SED, Micron provides not only outstanding performance, but also the peace of mind that confidential information stored on a laptop is secure. Wave is excited about this new partnership with Micron and we look forward to providing our customers with a high performance SSD with strong data protection capabilities."

The security and reliability of Microns C400 SED was designed for large corporations, government systems and other multiple-user networks that require maximum security without cumbersome workflow interruptions or decreased performance.

The C400s encryption key is protected within drive hardware—separate from the host. This is one reason why hardware-based encryption is superior to software encryption (an alternative solution that stores the encryption key in the computers memory, where its vulnerable to attack). Microns SED offers stronger security because the encryption key never leaves the drive. User authentication is performed by the drive prior to starting the operating system, ensuring independence from the operating system. Another disadvantage of software-based encryption is its dependence on the computers processor, which can degrade performance. In contrast, Microns C400 SED performs all encryption inside the SSDs controller, ensuring no system performance degradation.

"The C400 SED will help users and IT teams alike to sleep better at night. Weve leveraged our popular client SSD and partnered with the leading encryption management vendor to create a product that provides a solid defense against data theft," said Justin Sykes, Microns general manager of client SSD solutions. "With security breaches increasing for every type of user, this solution scales without sacrificing high performance or reliability."

The C400 SED SSD is available in 128-, 256-, and 512GB capacities, a SATA 6Gb/s interface, and 2.5 and 1.8-inch form factors. The drives sophisticated NAND management delivers sequential read and write speeds of up to 500 MB/s and 260 MB/s respectively — the same high performance as Microns popular C400. The drive will be sampling and in production in the fourth quarter of this year and will be available through Microns global distribution network.

* Weight: 4.8 lbs
* Dimensions: 13.5” x 9.6” x 1.1”
* MSRP: $849.99

Its also worth mentioning that ASUS informed us that Amazon.com has a rather attractive promotion going on after November 1, 2009. Anyone who purchases the UL80Vt-A1 from Amazon gets a $100 Amazon gift card.

The same promotion also applies to the ASUS UL50Ag-A2. Additionally, if you purchase an ASUS UL20A-A1 Amazon will include a $75 gift card. Details regarding this promotion were not available at the time of this writing, but you might want to check out Amazon.com for more information.

Build and Design
The UL80Vt has a classy design. With a height of only 1.1 inches it is certainly a thin machine, and the inward chiseled sides make it look even thinner. The lid is the most visually attractive part of the notebook with its brushed aluminum back and angled hinge design. The island-style keyboard also adds to the visual appeal; it sits flush with the surface of the notebook. Although the UL80Vts 8-cell battery is large the designers cleverly integrated it between the display hinges for a flush appearance. The UL80Vt has an understated look and fits in both home and work environments.

The UL80Vt has a plastic construction with the exception of the aluminum-backed lid. All visible surfaces are glossy which means dust and fingerprints show up easily; keeping this notebook clean is a chore. The plastics themselves are of reasonable quality.

Unfortunately the good news ends here. The UL80Vts build quality and construction are subpar. I was able to visibly twist the chassis using only modest pressure, and pushing down on the touchpad literally causes the chassis to sag and touch the surface it is resting on.

This unusually high amount of flex indicates that the notebooks internal frame is not strong enough. The lid also twists easily despite the aluminum back. Furthermore, the plastic screen benzel below the lid is very flimsy and can easily be pulled away from the screen about a half centimeter. Pushing on this area causes the screen to bend outward uncomfortably far. Lastly, the plastic trim above the keyboard is unsecured and has a few millimeters of up-and-down play. Overall while the build materials themselves are of reasonable quality the strength and construction of the UL80Vt are disappointing.

Screen and Speakers
The UL80Vt has a 14-inch display with LED backlighting, a 16:9 aspect ratio, and a 1366x768 resolution. Its glossy coating makes images look clearer at the expense of glare. The display has plenty of brightness but the contrast is low, making pictures look slightly washed out. Side-to-side viewing angles are adequate however are limited vertically; the display needs to be tilted just right to get an accurate picture. A better quality display would have been appreciated on a multimedia notebook like the UL80Vt.

The speakers are poor despite the Altec Lansing branding. They do not get loud enough and are very tinny. The headphone jack is fortunately static-free and the best way to get audio out of the notebook.

Keyboard and Touchpad
The UL80Vt has a chiclet/island style keyboard with extra space between keys. The keyboard is unfortunately mediocre and does not do anything well. While typing the keyboard feels loose as if it were merely resting on the chassis rather than being secured and has a cheap rattling sound, especially on the left side. Flex is also a problem on the left side. The tactile feedback is limited at best; there is not enough of it and key travel is too short. Moreover the keys are noisier than we prefer. As a result of these deficiencies typing is uncomfortable especially for extended periods.

The touchpad is also below average. Its glossy surface is difficult to track on and the single-piece button is somewhat noisy and difficult to press. I had to apply pressure at the far left and right edges of the button to get clicks to register.

Ports and Features
The UL80Vt has an adequate selection of ports, including HDMI. The notebook strangely does not have a Kensington Lock slot or built-in Bluetooth. All picture descriptions are left to right.

How To Take Care of your Laptop Battery

Laptop is currently a choice of many people to help various activities of daily work. However, not all Laptop users know how to treat a laptop and the batteries properly.  U.S. Consumer Product Safety Commission has recorded at least no fewer than 47 cases a smoky or burning laptop, since January 2001 to August 2006. 


Here are some tips to care for laptop battery that last longer: 
  • Laptop Batteries, Do not drop, knock, crushed by heavy objects, or piled on top. This would result in battery circuits become vulnerable to short-circuit occurs (shorted), which then lead to overheating. 
  • Do not place the laptop in the aera is very hot, such as in the hot sun or in the car parked in the open long enough during the day. 
  • Do not use the laptop battery and charger are not compatible. If not sure of the compatibility of a replacement battery or charger to use, contact the service from the laptop manufacturer related. 
  • Help prevent the contacts on the battery holder is loose with a variety of objects made of metal, such as paper clips, and so forth.
  • Wet or exposed to water, are things to avoid from a laptop or a battery. Although eventually will dry up and can function normally, the circuit inside the laptop or the battery will slowly rust which can cause damage to the battery itself. 
  • When using a laptop, avoid putting your laptop on soft surfaces, such as on a sofa, bed or carpet. because it will inhibit the flow of air at the bottom of the laptop and can cause overheating.
  • Make sure you understand how to use, store and charge the batteries and laptop that have been written in the manual.

Jade Dynasty Playing Tips The introduction of Esper

One of the fun features that can be used in Jade Dynasty is the Esper. What is Esper? Equip this esper is useful for your character, because the Esper can add a status grew in each level.

In addition, you can use the Esper makes Skyblades that can fly you. Another plus of Esper is to help you hunt down monsters as long as you are not on the computer.

Also your character will get EXP and item by itself!

Esper is the first time can be obtained at the City of the Sun or Kingdom of Heaven after you complete the Quest Mandatory. Of course this is not the first Esper Esper only will you get.
Another Esper can be obtained through Quest, Esper and other traders. Esper of the most difficult to obtain is the most powerful Esper.

Let us know Esper:

1. Main Bar Esper.
At the Main Bar Esper slots are special and only the skills and special items that can be put in the slot:

    * Skill Esper: Esper Only skill that can be put in this slot
    * HP: Only items that can add the HP can be put in this slot
    * SP: Only items that can add SP can be put in this slot
    * VG: Only items that can add Vigor can be put in this slot
    * EN: This is a slot which is very important that Esper running, ie Esper
    * Energy. Only items that can add Esper energy in put in this slot.

In addition there are three buttons that you can adjust the settings according to your wishes and the Keys to issue Skyblade you use.

2. The second bar Esper.
At the Bar Both Esper there were 10 slots that contain 3 for the goods you need when hunting like to add HP or SP, and the remaining seven slots to place skill-a skill that you need when hunting.
Everything in Bar Second Esper can set the time as you wish that you need, whether the goods when hunt supporters as well as skill.
For setting the bar Esper Second skill you can see the explanation below:

If you press the second button on the right Esper, Invigorate menu will appear. This menu is used to regulate the use of Pot, retrieval items, and range use of skill.

1. Setting Auto-Recover:
Setting percentage and time out you can adjust as needed you want.
* HP <= If your HP is less than 50% HP then you will automatically be added every 2 seconds.
* SP <= If your SP is less than 50% then automatically SP you will be added for every 2 seconds.
* Vigor <= If you Vigor less than 70% then automatically Vigor you will be added for every 2 seconds

2. The capture of goods,
You can arrange to pick up goods at the drop of a monster from the settings from here, either quest items, provisions or any other items.

    * All the items are: Take all the items in good dropkan by monster quest items, provisions or any other items.
    * No goods: If you want to focus on the hunt, you could checklist here, because you will not take goods in dropkan by monsters.
    * Goods are taken: this checklist if you just want to collect items that are used to add a provision to fraksimu donation.
    * Not taking things: You just take things other than goods provision.

3. Skill Settings
At the bottom is the skills menu. numbers in each box shows the Esper waiting period to use the skill again. Its good to see you guys cooldown skills to ensure these skills to work effectively. For example the skill has a cooldown for 1 minute, then these skills should be reused after 60 seconds, so as not to waste Spirit.

But, if you do not need this skill out continuously, you can add a second time according to what you want. If you prefer not using a Skill, you can check the option "Disable Skills". Once finished setting all the parts you can press the button "Confirm"

Well, the interesting feature is not it? Hopefully with this feature and an explanation, you can enjoy your new adventure at the Jade Dynasty! Congratulations adventure in the World Jade Dynasty.

Apple MacBook Air 11 Mid 2011 Subnotebook Review

The smallest portable and cheaper than Apple currently offers is called the MacBook Air, 11 weighs less than a kilogram and is only 1.7 cm at the thickest point. Externally: aluminum unibody case. Inside: Sandy Bridge CPU, along with the SSD offers superior performance.

Apple has stuck to this policy for years: new trends, but do not jump on any bandwagon going. " So, for example netbook hype the past two years there is almost no sign of Apples product portfolio. Their response was to the IPAD, which produces results that we all know.

The MacBook Air back to 2008, its first generation, as the theme of "ultrabooks" that is especially thin laptops under $ 1,000, is currently being discussed by many manufacturers, it will be another knowing smile to remember the faces of computer users. In addition, 11 officers from the air price is $ 999, which is an incredible coincidence!

Specifications Apple Macbook Air 11 inch 2011-07 MC969D/A :
  • Processor : Intel Core i5 2467M 1.6 GHz
  • Mainboard : Intel ID0104
  • Memory : 4096 MB, DDR3 1333MHz

  • Soundcard : HD Audio
  • Connections : 2 USB 2.0, 1 DisplayPort, Thunderbolt (Mini-Displayport)
  • Networking : Broadcom 802.11n (abgn), 4.0 Bluetooth
  • Size : height x width x depth (in mm): 17 x 300 x 192
  • Weight : 1.07 kg Power Supply: 0.19 kg
  • Battery : 35 Wh Lithium-Polymer
  • Price : 1149 Euro
  • Operating System : Mac OS X 10.7 Lion
  • Additional features : Webcam: FaceTime Cam, 12 Months Warranty
Case
For the 11-inch laptop, like its big brother the MacBook Air 13, Apple uses the same chassis that was made so that the air in 2010. And almost a year later, the aluminum unibody is still one of the best materials the most demanding of today could call his own. The look, feel, quality of construction - there is simply no real points of criticism here.

On the contrary, the more you play with the laptop, the more satisfied you will receive in this regard. Details about the case can also be found in our previous test of the machine from 2010, which is of identical construction.

The keyboard is always backlit LEDs, whose brightness can be set at many different levels, such as screen brightness. Compared to 13 inches in the air, youll see almost the same layout and key size. Only the ranks of F and the extra features in it has been made thinner.

Connectivity
As with the Air 13-inch, Apple has added a port 11 Thunderbolt Air The other port remains unchanged from the previous model, meaning that you have to do with two USB 2.0 ports, ports and port helmet. Compared to the current 13-inch air, you must also do without an SD card reader.

This theme was Thunderbolt should be noted that there is much to benefit from this port, at the time. Only Apple provides an auto-compatible 27-inch (including additional ports), will cost about 900 euros. Lightning port can also be used for a mini-DisplayPort. Then, using the appropriate cable or adapter, a traditional display may also be connected to Air. Further information can be found in our review of the port 13 Thunderbolt MacBook Air

Communication
WLAN, which follows the 802.11 a / b / g is part of the standard material for this series, and Bluetooth 4.0. There is no RJ45 network port to be found, it was probably too big to Air. Apple does offer a suitable adapter for USB and slow it for a price of course (approx. 30 euros) or you can use the screen above Thunderbolt with its LAN port.

Guarantee
The manufacturers warranty for Apple MacBook 11 is 12 months. You can also purchase extended warranties of 12 or 24 months, including telephone support.

Display
Although the basic details of the screen has not changed - 11.6 in. Display, 1366 x 768 resolution, a shiny surface - it is still a new panel that has been integrated in this model. In our model of identifying the review committee LP116WH4-TJA3 and is manufactured by LG Philips. In some Internet forums, there are messages on a second screen version (LTH116AT01A04) that can be manufactured by Samsung.

Our LG screen has a maximum brightness of 355 cd / m² in the tests with the Mavo Gossen meters. The average brightness is still very bright 318 cd / m², making it one of the best in its class of machine. The black value of only 0.56 cd / m² is also excellent with an outstanding contrast ratio of 634:1.

Compared to its predecessor in 2010, which was equipped with a screen LTH116AT01A01, we see an improvement in brightness (up to 340 cd / m², average of 296 cd / m²).

AnandTech revised MacBook Air 11 with Samsung screen (LTH116AT01A04) in their machine. The panel shows a slightly worse black, but a higher peak brightness of 0.61 and 386 cd / m², respectively. No rules have yet been observed, which would decide which of the two possible display types used in the configuration.

A look at the color space can be represented produce any surprises. sRGB can not be completely covered, the predecessor of the machine of 2010 was more or less the same league, while the screen of the MacBook Air 13 in 2011 (LP133WP1-TJA3) covers practically the same size as the screen 11 inches from the same manufacturer.

The stability of viewing angles are quite comparable with the 13-inch model we tested, putting it slightly above average among the last laptops. Horizontally, even very wide viewing angles as possible without causing major problems, and in vertical direction, the more it deviates from the ideal straight on viewing angle, the picture is more wash or affected by the effect of well-known inversion.

Performance
A new processor Sandy Bridge gets its chance in this 11-inch MacBook Air, as in the 13 inch version. Starting level is a Core i5-2467M with a base speed of 1.6 GHz. The chip is slower than i5-2557M Processor (1.7 GHz), which is the starting point for the 13-inch model. As with the larger model, there is an option to switch to Core i7-2677M with 1.8 GHz.

Taking care of the graphics you need an Intel HD 3000 Graphics intregrated units in the CPU. But even here, the difference between a version of Apples 256 MB and 384 MB of shared memory. This is directly proportional to the amount of RAM in each model.

So begins 2 GB version (which are closely welded to bottom, not upgradeable!), Dynamic memory that is available on the GPU is limited to 256 MB, but the 4 GB of installed RAM, HD 3000 graphics may be a larger part of the series . But this does not change anything in the graphics department. Great video memory is usually necessary or useful for a game or multi-monitor setup.

CPU Performance
To judge the performance of the new Intel Core i5-2467M processor, we return to our CPU benchmark standard tools using Windows via Boot Camp. SuperPi in 32 M-test (calculation of exactly 32 million decimal places) MacBook Air with i5-2467M CPU needed just 903 seconds.

To compare: Intel Processor Arrandale ranks 460 / 520M at about the same level, while the new Intel Core i3-2310M processor Sandy Bridge is itself a bit longer (940-980) to complete the task. Apple MacBook Air 13 but with a little more powerful i5-2557M calculates much faster at 763 seconds, put it in the same league as Intel Core i5-2410M processor.

Looking back on the air 11 from 2010 with its SU9400 processor provides a powerful demonstration of improved performance: 1936 seconds, which means that the calculation of the speed is more than doubled.

While SuperPi uses only a single nucleus, the son wPrime calibration tool uses all the CPU. With 869.7 seconds in the test of 1024 m, our chip is just behind i3-2310M processor. The air stream 13 is also ahead here, with 764.6 seconds (i5-2557M). The CPU 13 of the Air SL9400 2010 was beaten back by almost 50%.

In Cinebench R10 (64 bit) CPU test only Air scored 3610 with 2467M processor, which can stand in front of Intel 2310M. The Air 2557M processor reaches 13 with 4201 points from the set at almost the same level as the mid-range processors 2410M. In the same test, but 32-bit mode, the new Air New beats its predecessor in 2010 by about double.

The results of multi-threaded Cinebench rendering test of (64 bits) is basically the same. With 7188 points in the Air from Apple, 11 in 2011 is just behind other notebooks with Intel Core i3-2310M processor. But with his 13 Air CPU 2557M is a part of the ground lost in the test score of 8266 points, which is a much better result than the air 11, but it is still clearly behind the other machines on the CPU 2410M.

Compared to the predecessor of Air 11, we again had to settle for 32-bit mode because of the lack of comparable data. With 5946 points to 2852 points, look back nine to beat the previous model from 2010 with SU9400 CPU with more than 100%.

In the end, ran Cinebench CPU R11.5 last. 1.9 points, ranking CPU 2467M almost the same level as Arrandale i3 330M CPU, the chip in late 2310 m modern. Air 2010 SU9400 reaches 0.9 points, while the ignition, surprise surprise, only about half of the performance of the new entry-level CPU 2467M.

Geekbench - CPU performance Mac OS X
The small ultra-thin notebook from Apple may also show its processing power when running Mac OS X. Especially when compared to the previous Core 2 Duo, Core i5 is considerably faster and can even get a head start on the 2.4 GHz Core 2 Duo P8600 MacBook Pro in the 13 from 2010.

Throttling
We want a closer look at the limitation of subject because there have been some complaints about this in the past with other laptops from Apple. Again, we used Windows Boot Camp as our test platform, as analytical tools it offers, and MacOS.

I5 Intel 2467M used in this notebook, as its portfolio of adult colleagues Sandy Bridge CPU, the speed of bandwidth, in this case from 1.6 to 2.3 GHz, depending on the number of threads / cores on time. How does this dynamic range can be used in turbo depends more on the cooling power of a laptop case.

While in both cores idle still regularly come from 2299 MHz (high performance profile), the speed of the two nuclei falls to 1999 MHz under stress, ie in the SuperPi and Cinebench R10 test single CPU. Sometimes, just for a short time, an acceleration of a nucleus with its maximum at 2.3 GHz are observed.

In the multi-threaded Cinebench R10 and R11.5 CPU tests in Cine, the two cores were stable in 1999 MHz, consistent with our observations, although the experiments were carried out in an infinite loop.

He took the maximum Prime95 stress scenario and Furmark to win the frequencies into submission. Shortly after starting the stress test, we noticed the speed of 1199 MHz for both cores. About an hour after the pressure of the stress test finally identified after repeated, short-term reduction in CPU speed of 799 Mhz.

And interesting, we found the temperature of the CPU with HWMonitor always remained uncritical area of ​​about 80 ° C. The power adapter is, however, touches the limits of the ability of suppliers of energy (45 watts), with peak values ​​up to 44.9 watts during the test. This could be a possible explanation for the limitation that we have seen repeated.

We also had a detailed look at the pattern of behavior of the benchmark in the last MacBook Air, for example, showed an interesting trend to produce better results over time or with higher fan speed.

We start with the single CPU test Cine R10. In the test circuit is scored for 3517, 3562, 3591, 3565 and 3610 points. The fan continues to increase its speed to the end of the first test (from 80 ° C). Maximum temperature of the CPU, there was only about 80 ° C (second run-through), while after round temperature of about 70 ° C. No signs of strangulation here, done everything there is a slight improvement in baseline scores.

We tested the same model of analysis based this time in the film R10 benchmark multiple CPUs. It was noted the next set of results: 7024, 7141, 7126, 7117 and 7188, the fan reaches a speed of 5000 rpm in the third run-through and more importantly, the CPU temperature remained constant at just under 90 ° C thereafter.

In Cinebench R11.5 the latest processors, we saw an almost identical picture, with a score of 1.31, 1.91. 1.92 and 1.92 points. In the first run through, we saw CPU temperatures up to 97 ° C. After that, the fan speed increased, peaking at 6500 rpm, with which you can keep the CPU temperature 80-84 ° C. stable

Then also prepared a series of tests for MacOS X Cinebench, if only we have been able to measure the CPU temperature and fan speed with SMC fancontrol tool. In a single CPU test R10 Film, we observed the following series of results: 3142, 3194, 3150, 3159 and 3162.

In the first run through, the fan starts to increase speed of about 80 ° C to count. This prevents an increase in temperature above 80 ° C, after smcFanControl. In addition, the fan speed never exceeded 3500 rpm for our observations.

In multi-CPU Cinebench R10 test, we recorded the following result set: 6452, 6522, 6511, 6493, 6510, 6490 and 6520.

The first training started to increase the fan speed of about 90 ° C point. The fan speed is increased by subsequent run-through, and the CPU temperature was held constant significantly less than 90 ° C.

With MacOS as with Windows, a higher temperature in the test faster CPU Cinebench Cinebench R10 R11.5 in multi-CPU test. The fan starts quickly and has already reached its maximum at 6500 rpm for the first run through, keeping the CPU temperature below 80 ° C. It is much less than the same test when you run Windows, for example. Results: points 1.92, 1.93, 1.93 and 1.94.
