  • Product image may represent a design model.
  • 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.
  • A kibibyte (KiB) means 210, or 1,024 bytes, a mebibyte (MiB) means 220, or 1,048,576 bytes, and a gibibyte (GiB) means 230, or 1,073,741,824 bytes.
  • 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 be different from the MTTF.
  • Read and write speed may vary depending on the host device, read and write conditions, and file size.
  • SIE: Sanitize Instant Erase. SIE is compatible with Sanitize Device Feature set. Sanitize Device Feature set is the standard prescribed by T10(SAS) and T13(SATA) committees of American National Standards Association(ANSI), which makes it possible to invalidate the data recorded on the magnetic disks at a blink.
  • "2.5-inch" and "3.5-inch" mean the form factor of HDDs or SSDs. They do not indicate drive's physical size.
