The New Heavyweight Champion in the the Capacity Arena
The World’s First 9 Disk HDD*

Using the world’s first 9-disk Helium-sealed design, the MG07ACA Enterprise Capacity SATA HDD provides up to 14TB of conventional magnetic recording (CMR) capacity and 7,200 rpm performance. The industry-standard 3.5-inch form-factor integrates easily into cloudscale storage infrastructure, business-critical servers and storage, and File and Object storage solutions.

The MG07ACA Series utilizes Toshiba precision laser welding technology to seal helium inside the 9-disk mechanics for the life of the drive. The helium-sealed design reduces aerodynamic drag to deliver a lower operational power profile, helping to achieve TCO objectives for cloud-scale and software-defined data center infrastructure.

Advanced Format (AF) is the standard that improves formatting efficiency by increasing the length of HDD data sectors to be longer than their traditional size of 512 bytes. The Advanced Format standard was formulated by the International Disk Drive Equipment and Materials Association (IDEMA) in which Toshiba Electronic Devices & Storage Corporation and other HDD manufacturers participate. By establishing the Advanced Format standard, IDEMA aims to ensure that the storage devices supplied by various companies will be compatible with file systems and operating systems (OS) generations that support AF sector technology.

Advanced Format improves formatting efficiency and the reliability of recorded data by increasing the length of data sectors and relative strength of the error detection and correction algorithms. The generation one Advanced Format standards stipulate a physical sector size of 4,096 bytes and includes the ability to logically emulate the older 512-byte sectors (sometimes called "512e")in order to maintain compatibility with applications or hardware which demand conventional 512-byte sector technology. During emulation, when the host sends the disk drive data to be stored in increments of 512 bytes, the disk drive places the emulated 512-byte sector at an appropriate position within a larger physical 4,096 bytes sector and then writes the 4,096 bytes sector to the disk media.

Some file systems and operating systems generations have advanced to support the physical 4096-byte sector as the logical sector size. Such host systems are called "4K native (4Kn)" capable. Since both the physical and logical sector length are 4096 bytes, emulation of the older 512-byte sectors is no longer required, allowing the 4Kn host to use the available 4Kn disk storage more efficiently. We have made available HDDs of the 512-byte emulation type, the 4Kn type, and the 512 native type, to provide the sector technology that will fit the host systems’ specification.
