10TB HDD, Record for Toshiba

Toshiba Electronic Devices & Storage Corporation announced the addition of an 10TB [1]) SATA model to its MG06 series of 3.5-inch [2], enterprise capacity class HDD.

Shipments start from today.

The continuing progress of digitization, most recently the quickening expansion of IoT and the increasing reliance on cloud services means that more information is being generated and stored than before, and that the rate of its creation only continues to increase. The data centers and cloud-based services that use this data constantly require higher-capacity, higher-performance HDDs.

MG06 series HDDs deployed an improved magnetic recording head and disk magnetic layer, and now deliver up to 10TB of capacity with air-based HDDs, a 25% [3] increase over the maximum capacity of the earlier MG05 series. The HDDs achieve a sustained transfer rate of 237MB/s [4,5], and a 25% [6] improvement in operating life that boosts MTTF [7] to 2,500,000 hours. These improvements in capacity, speed and reliability can contribute to the lower system TCO.

The new HDDs support both industry-standard 512 emulation (512e) and 4K native advanced format sector technologies, for use in legacy applications requiring 512 sector lengths using aligned-write environments, and are also suitable for the latest generation of servers and storage systems.

Customers also can select 512e models supporting SIE (Sanitize Instant Erase), which realize fast invalidation of data recorded on the disks, allowing for efficient disposal and reuse.

Notes
[1] Definition of capacity: Toshiba defines 1TB as 1,000,000,000,000 bytes. A computer OS, however, reports storage capacity using powers of 2 for the definition of 1GB = 230 = 1,073,741,824 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and OS, such as Microsoft OS and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
[2] 3.5-inch refers to the form factor of HDDs. It indicates the size of the disks, not the HDD’s physical size.
[3] Comparison between MG05 series: 8TB and MG06 series: 10TB
[4] Read and write speeds may vary depending on the host device, read and write conditions, and file size.
[5] 1MB is 220, or 1,048,576 bytes.
[6] Comparison between MG05 series: 2 million hours and MG06 series: 2.5 million hours
[7] MTTF is not a guarantee or estimate of product life; it is a statistical value related to mean failure rates for a large number of products, which may not accurately reflect actual operation. The actual operating life of the product may differ from the MTTF.
