Toshiba MG10F hard drives

03.10.2023

Manufacturers of traditional hard drives continue to push the envelope, introducing devices with capacities up to 22 terabytes. After Seagate and Western Digital, Toshiba presented its solution in this segment. The new MG10F series of drives not only continues the tradition of the Toshiba MG10 line with 3,5-inch drives, but also raises the capacity bar to 22 terabytes.

Toshiba MG10F are enterprise hard drives of the second level (nearline), offering options from 2 to 22 terabytes, operating at speeds of 7200 rpm and providing a choice between SAS interfaces with a bandwidth of 12 Gbit/s and classic SATA with a bandwidth of 6 Gbit/s. s, starting from 1 terabyte.

When it comes to recording methods, Toshiba takes a few different approaches in this line. For disks up to 10 terabytes inclusive, traditional perpendicular recording (PMR) and an air hermetic block are used. Disks with a capacity of 12-16 terabytes are switching to a helium hermetic block and using platters with the same recording technology. Models with a capacity of 18, 20 and 22 terabytes use recording with microwave support (Flux Control Microwave Assisted Magnetic Recording, FC-MAMR). All drives are designed to operate 24/7 and can withstand loads of up to 550 terabytes per year.

Depending on the disk capacity, the cache memory size can vary: up to 2 terabytes - 128 megabytes, up to 14 terabytes - 256 megabytes, and models with a capacity of 16 to 22 terabytes are equipped with 512 megabytes of DRAM cache. The data transfer speed of the smallest disks (1 and 2 terabytes) reaches 204 megabytes per second, and for the largest version it grows to 284 megabytes per second. This is comparable to the performance of Seagate IronWolf Pro drives of the same capacity (285 megabytes per second), but slightly lower than WD Gold (291 megabytes per second).

Although the use of tile-structured recording (SMR) would increase the maximum capacity of the drives by 15%, Toshiba does not use this technology in this line. While Western Digital offers 26 terabyte drives with SMR technology. Toshiba previously announced a similar model, but it never appeared on the market.

Deliveries of Toshiba MG10F drives with a SAS interface have already begun, and SATA versions will appear later, in the fourth quarter. Encryption options (Self-Encrypting Drive) and secure erasure (Sanitize Instant Erase) are also available.

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 ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. 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, ... >>

Mornsun LD/R2 ultra-compact power supplies 14.04.2021

Mornsun has updated its popular LD(LDE) board mount line of miniature AC/DC converters with the next generation LD/R2 family. A feature of the new AC / DC is a reduced size and reduced cost compared to its predecessors.

IP with power of 3, 5, 10, 15, 20 W operate in an extended input voltage range of 85...305 V (AC) at temperatures from -40 to +85ºC and have reinforced isolation "input-output" 4000 V (AC). According to EMC, the power supplies correspond to class B (CISPR32 / EN55032) and are equipped with built-in protection against exceeding Uout, against overload and short circuit; power consumption at XX - less than 100 mW. There is a choice of models for mounting on the chassis (with terminals) and on the DIN rail. The above parameters make it possible to consider the LD/R2 IP as one of the best in its class.

The products are designed for industrial automation and control devices, for use in smart home systems, IoT applications and anywhere a compact power supply with good EMC and high performance is needed.
