This corresponds approximately to the 44-times the capacity of today’s LTO tapes of the fourth generation. The researchers believe not, however, that the possibilities are exhausted with it. "This demonstration is an important step towards the development of tape storage with a recording density of 100 billion bits per square inch," said Evangelos Eleftheriou, head of the storage technology research at IBM Research in Zurich.

"The tape technology to their cost advantage over disk storage and flash can continue to maintain and continue to allow affordable and robust data protection," said Cindy Grossman, vice president for IBM’s tape storage and archiving systems. This is particularly true for the remaining uses of magnetic tape, such as securing large amounts of data that would not regularly required, such as data and video archives, backup files and backup copies as part of disaster management or legal compliance.

In terms of cost per gigabyte tapes are in long-term storage of data, IBM said in a fifth to one tenth of current hard disk storage. Another advantage is that unlike continually rotating disk tape cartridges require no power when not accessed.

Microsoft is investigating the possibility of Xbox 360 game consoles of the type to use in hospitals. There they could read electronic patient data and filter and make it visible on screens in the hospital room for nursing staff and patients. This has Microsoft announced at an event of its Health Care Division Health Vault in Beijing.

Microsoft engineer Desney Tan that the consoles are cheaper than those usually used for that purpose hardware. In addition, patients could be playing or access the Internet – possibly with gestures on the next input system Natal.

Microsoft’s health services are developing also in other directions. So will you give patients the tools with which they identify their calorie intake by cell phone or count their steps. They too should be able to easily access their medical records. MyLife thus uses the tool that runs on Windows Mobile smartphones, embedded devices such as cameras, motion sensor and microphone to capture data such as blood pressure or weight and to log activities such as sports and eating.

Eric Chang, manager of Microsoft Asia, says he dream that users retrieve information about their food – calories, nutrients contained, risks for allergy sufferers – because of a photograph could. As a first step, he imagines tags, which could provide themselves food. It is natural for plants from the garden, hard by a farmers market or grocery store. But if there is no other just as McDonald’s dining area there, the user can then at least monitor the deterioration of his physical condition.

Seagate unveiled the fourth generation of its 2.5-inch enterprise hard drives. The model Savvio 10K.4 will consume 4.6 watts in idle up to 60 percent less electricity than conventional 3.5-inch drives. According to the manufacturer of mass storage is working with 10,000 revolutions per minute.

Savvio 10K.4 hard drive is the server it with 450 or 600 GB of disk space (Image: Seagate).

The Savvio 10K.4 appear in capacities of 450 GB and 600 GB. As an interface either a SAS 2.0 interface comes with a transfer rate of up to 6 Gbyte / s or a Fibre Channel port with a speed ranging up to 4 GB / s applications. The cache is 16 MB.

The mean time between failures (Mean Time Between Failures, MTBF) is in the 24-hour operation, according to Seagate for two million hours. When reading the access time is 3.89 milliseconds and 4.54 milliseconds be in writing. The Stobresistenz the manufacturer gives a maximum of 40 G at the company.

Like its predecessor, the Savvio 10K.3 2.5-inch hard drive with Full Disk Encryption Privacy (FDE) equipped according to U.S. government standards. The integrated Power trim technique manages the power consumption of the storage media is idle and administrators can set different power management modes.

According to the company Seagate Savvio 10K.4 delivers soon from its OEM partners. A price for the server hard drive has not called the manufacturer to date. The warranty is five years.

Intel introduces SSD for entry-level $125

The model X25-V offers a storage capacity of 40 GB. It has a maximum read rate of 170 Mbytes/s and a write speed of up to 35 MByte/s. It also dominates the Windows 7 supported TRIM command.

Intel has expanded its portfolio of Solid State Drives to an entry-level model called X25-V. This is a stripped down version in July 2009 announced the X25-M series with 34-nanometer NAND flash memory. The SSD is available now at a price of $ 125 on the market.

The 2.5-inch X25-V model is working with MLC memory cells and a SATA II interface. It offers a storage capacity of 40 GB. The read speed is up to 170 MB/s slower than achieved in the X25-M series, the read rates of 250 MByte/sec. The maximum write speed of 35 MByte/s – half of the achievements of the X25-M series value.

The mean time between failures (Mean Time Between Failures, MTBF) is Intel, with 1.2 million hours (136 years). The Sto?resistenz maximum of 1500 G. In operation, the drive consumes 1.5 watts. At rest, it is content with 0.75 watts. In addition, dominates the SSD which is supported by Windows 7 TRIM command, which ensures a consistently high level of readiness to perform a Solid State Drive.

Without TRIM support for SSDs can use the service after a prolonged partial decrease considerably. The reason for this lies in the physical properties of the flash cells. Flash memory can be described only with no wait states, if the cells are empty. Since the operating system files but only delete the contents of the file system and the controller of the SSD of this deletion will notice anything, it must delete the access back into the cell, these first before he can describe it. Per TRIM command divides the operating system with the SSD controller, the data blocks are no longer used, so that it can delete the unused cells of rest, in order to later describe without loss of performance again.

Kingston sells under the name V SSDNow an identical model of the Intel SSD. A similar review is available here.

Yakobson said the bucky balls filled with hydrogen can theoretically the same as the powder store. He said, "not too hard, they may gather synthetic molecular crystals or form a fine powder. The ball is full of hydrogen molecules Buck crystal or powder, under certain conditions, should be able to release pure hydrogen for fuel cells or other forms of engines. "

We can imagine the results if successful in the civilian economy was a large-scale use of it, how our lives will be a huge change. Light vehicles can use clean hydrogen fuel, the air will become fresh. Fuel cell will be more universal, the number of electronic products will be access to safe portable high-capacity fuel cells. Sky charge a cell phone is not two or three; enjoy MP3 and cuts off power when not regularly; Digital SLR Camera full 1,2 G memory card, battery, or full of; books battery life is no longer only a few hours; In addition, friends of the electric car ride, do not need more than a dozen 20 kg per day Kangshang a mound battery climbing stairs of the all in all, just get a bottle of safe light "bucky balls of hydrogen fuel filling" , power-off time, simply unscrew the lid, add fuel, everything buttoned up. This is a wonderful blueprint ah.

Ate hydrogen fuel cells emit pure water "big bus" is expected to debut Expo

This new green energy fuel cell cars is no longer the patent, has become a "big bus" friends. Recently, information came from Tongji University: the school and SAIC jointly developed by companies such as fuel cell transit buses have been gearing up, is expected to be the core of the 2010 World Expo exhibition and public meeting.

Experts point out that the ever-changing new energy technology in the green area of public transport buses has become an important global R & D goals. For example, the "battery" operation principle of a super capacitor car 11 road transportation in this city, across the board application online. The research team trying to fuel cell power system has a "do not eat only the oil absorption of hydrogen, fuel cell drive depends," the chemical reaction, discharge of only the "pure water" and so on, is seen as the future direction of the automotive industry is expected to full use of existing parts and components for the Shanghai Resource Development of "Green" stocked with brand-new way.

Fuel cell power technology is not unfamiliar. Now a new generation of China's independent intellectual property rights fuel cell car, the power system has a maximum output power to 88 kW, maximum speed increased to near 150 km. How will the more mature technology "transplanted" to the required more powerful, more complex operating environment of transit buses on a research focus.
