1095

Toshiba Corporation’s Storage & Electronic Devices Solutions Company today announced the launch of a new line-up of HDDs, “MN Series”, for network attached storage (NAS) applications. Shipments start from today.

The new “MN Series” HDD line-up delivers up to 8TB capacity in a 3.5-inch form factor with a SATA interface. The drives are designed for 24/7 power-on operation and have a rated annual workload of 180TB transferred. They feature rotational vibration compensation technology and are suitable for use in home NAS and small office/home office (SOHO) NAS applications. The drives also have an 128MiB buffer, and the 8TB model achieves a data transfer rate of 230 MiB/s[5].

Notes

[1] Definition of capacity: Toshiba defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes.  A computer operating system, 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 operating system, such as Microsoft Operating System and/or pre-installed software applications, or media content.  Actual formatted capacity may vary.

[2]”2.5-inch” and “3.5-inch” mean the form factor of HDDs or SSDs. They do not indicate drive’s physical size.

[3] Workload is a measure of the data throughput of the year, and it is defined as the amount of data written, read or verified by commands from the host system.

[4] A mebibyte (MiB) means 220, or 1,048,576 bytes.

[5] Read and write speed may vary depending on the host device, read and write conditions, and file size.

[6] MTTF (Mean Time to Failure) 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. Actual operating life of the product may differ from the MTTF.
