TOSHIBA REVIEW

随着监控系统市场的持续扩张，大容量、高性能机械硬盘（HDD）的需求日益旺盛。这些硬盘被运用在多种形式的视频录像设备中。
为了满足不断增长的市场需求，东芝对其DT02-VH系列监控硬盘做了进一步的提升。4TB和6TB成为可选容量点，它们均采用了Shingled Magnetic Recording（SMR）技术。

The capability of hard disk drives (HDDs) to store and provide access to large volumes of digital data with an appropriate latency time at low cost is resulting in increasing demand for HDDs with higher recording density for use as information storage devices supporting the development of high-level machine learning and artificial intelligence (AI) technologies.

Large-capacity HDDs that allow data centers to store huge volumes of electronic information have become increasingly important as a key product for the development of information infrastructure in recent years. What is shingled magnetic recording (SMR) technology that increases the capacity of HDDs by overwriting data on a recording track analogous to the shingling of a roof?

With the fast-growing prevalence of cloud services, the volume of data generated is increasing. This, in turn, is creating expanding demand for large-capacity HDDs for data centers. What are technologies that realized the large capacity HDD of 16 Tbytes using CMR?

The Toshiba Group is offering various solutions aimed at expanding the CPS through the development of hard disk drives (HDDs) that can hold large volumes of valuable data, as well as semiconductor products that can not only process these data but also control edge devices based on the processing results.

The trend toward digitization of information in society and the emergence of the Internet of Things (IoT) have been adding momentum to the information explosion in recent years.

Toshiba has remained at the forefront of the storage industry for more than 40 years and offers a wide range of storage technologies, including hard disk drives (HDDs), NAND flash memories, and solid-state drives (SSDs), as well as storage solutions applying these technologies. In the present era, often referred to as the “big data era,” digital technologies are showing unprecedented expansion and storage products have become one of the most vital components of society.

Object storage, a new storage system that enables large-scale storage systems to be constructed and managed at low cost, has recently been spreading in response to the explosive growth of digital data.

With the continuing increase in the volumes of data and complexity of data processing handled by facilities in both the private and public sectors, large-scale parallel and distributed systems, which can process data distributed to a large number of computers in parallel, are necessary to deal with large volumes of diverse data at high speed.

The use of solid-state drives (SSD) utilizing NAND flash memory is rapidly expanding in the field of cloud computing, which is highly dependent on enterprise servers and storage devices.

The transition of storage products from hard disk drives (HDDs) to solid-state drives (SSDs) has accelerated with the widespread dissemination of thin and light mobile PCs and tablets.

Toshiba has developed the MQ03ABB300 four-platter 2.5-inch hard disk drive (HDD) with a capacity of 3 Tbytes, the largest capacity in the market for HDDs with a 15 mm height form factor^(*1).

The information infrastructure society has been undergoing further major changes in recent years.

The increasing volumes of data accompanying the rapid expansion of cloud services and big data in recent years have given rise to the need for data center systems with higher speed and larger capacity in order to efficiently provide network services.

In the notebook PC market, hard disk drives (HDDs) with a large storage capacity are required for the recording and reproduction of large-volume contents including high-definition videos, while also satisfying mobile performance requirements.

With the growing importance of information security, demand has been increasing for the implementation of appropriate security functions in storage devices such as hard disk drives (HDDs) and solid-state drives (SSDs) according to their applications.

The use of solid state drives (SSDs) in enterprise servers and storage systems for network computing has been expanding due to superior performance, such as ultrahigh levels of input/output operations per second (IOPS) and IOPS per watt, compared with those of conventional hard disk drives (HDDs).

Solid-state drives (SSDs) using NAND flash memory have several advantages, including higher data transfer rates, higher shock resistance, and lower power consumption, when compared to hard disk drives (HDDs).

The hybrid drive, which combines bit cost advantage similar to rotating media with high performance close to that of NAND flash memory, has recently been attracting attention as a new storage device.

Hard disk drives (HDDs) for enterprise use are primary storage devices installed in mission-critical information systems such as servers and storage systems.

In the latest hard disk drives (HDDs), advanced high-performance technologies for the actuator and servo control are required in order to achieve not only accurate positioning control on data tracks with a pitch of less than 100 nm but also high-speed access onto another data track within a few milliseconds.
