WD's thinnest hard drives

05.05.2013

Western Digital today announced that it has begun shipping 2,5-inch WD Blue hard drives and WD Black hybrid drives (SSHD) to electronics manufacturers in 5mm thick cases. The vendor claims that these are the first drives on the market with such dimensions. To create these ultra-thin hard drives, our engineers had to design them from scratch," said Matt Rutledge, WD Vice President and General Manager, Customer Storage Business.

The new drives are designed for ultrathin portable devices and high-density computing systems. The maximum capacity is 500 GB. Drives can be placed in standard bays (for 9,5mm devices), but there will be free space. The new type of compact connectors SFF-8784, which was used in new WD drives for the first time, made it possible to reduce the thickness of hard drives. These connectors provide power and data transfer between the SATA controller and the drive, the company explained.

"Ultimately thin, and a compact interface connector opens up a wide range of opportunities for computer platform developers. In addition, due to the small size, it was possible to reduce the weight of the drives by 36% compared to standard 9,5 mm hard drives," said Rutledge.

New devices in working and off states are able to withstand shock accelerations up to 400g and 1000g, respectively. This was made possible thanks to the use of new miniaturization technologies, which maximized the free space inside the drive case, expanding the limits of permissible vibration amplitude.

The company did not specify the cost of new drives. The vendor plans to inform about the start of sales of devices in Russia and the recommended prices additionally. In November 2012, the A*Star Data Storage Institute announced the development of a 2,5mm thick 4,98" hybrid drive that holds 1TB of data. However, it is not yet on the market, unlike WD devices. It is planned to start production this year.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Lead is stronger than steel 01.02.2021

Lead is a very soft metal that can be easily minted and bent, but only under normal conditions. When extreme pressure is applied to lead, it becomes ten times harder than steel.

Scientists created extreme pressure using a laser system at the Lawrence Livermore National Laboratory, and subjected it to lead. The metal found itself in conditions typical of the Earth's core - the pressure inside the metal was about 400 gigapascals.

The scientists, led by Andrew Kreiger of Lawrence Livermore University, observed fluctuations in lead, which was under incredible pressure.

"The increase in vibration was relatively slow - our sample was calculated to be two hundred and fifty times stronger than lead under normal conditions. This means that lead under extreme pressure can be ten times harder than the highest strength steel," says Kreiger.

Experiments have shown that high pressure changes the structural properties of lead - the metal rearranges the crystal atomic lattice, turning into an incredibly hard material. This discovery can be used in industry - scientists are sure.
