Mobile Thin HDD



Toshiba's MQ01ABU-BW series of self-encrypting, FIPS 140-2 compliant 5,400 rpm HDDs (SED) deliver up to 500 GB of data storage capacity in a ultra-compact 2.5-inch 7mm height form factor. The MQ01ABU-BW leverages Toshiba's Wipe security feature which automatically erases data when the HDD is accessed by an unregistered system. Unlike software-based encryption which relies on the system CPU for encryption processing, the MQ01ABU-BW leverages its onboard crypto-processor to encrypt at full interface speed without impacting system level performance. With FIPS 140-2 level 2 compliance, Toshiba's MQ01ABU-BW offering provides tamper-evident labeling to deliver high level of security.

  • 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.
  • Toshiba defines "RoHS-Compatible" products as products that either (i) contain no more than a maximum concentration value of 0.1% by weight in Homogeneous Materials for lead, mercury, hexavalent chromium, polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs) and of 0.01% by weight in Homogeneous Materials for cadmium; or (ii) fall within any of the application exemptions set forth in the Annex to the RoHS Directive (Directive 2011/65/EC of the European Parliament and of the Council of 2011 on the restriction of the use of certain hazardous substances in electrical and electronic equipment). "Homogeneous Material" means a material of uniform composition that cannot be mechanically disjointed (meaning separated, in principle, by mechanical actions such as unscrewing, cutting, crushing, grinding and/or abrasive processes) into different materials. Examples of "Homogeneous Materials" would be individual types of plastics, ceramics, glass, metals, alloys, paper, board, resins and coatings.
  • Toshiba defines halogen-free and antimony-free SSD and HDD products as those meeting all of the following requirements: (a) containing bromine (Br) and chlorine (Cl) at no more than 900 parts per million (ppm) by weight for each element, and containing bromine and chlorine in an aggregate amount not exceeding 1500 ppm by weight; and (b) containing no more than 1000 ppm antimony (Sb) by weight. For the avoidance of doubt, Halogen-Free/Antimony-Free SSD or HDD products may not be entirely free of bromine, chlorine, or antimony, and may contain other element of the halogen family.
  • Read and write speed may vary depending on the host device, read and write conditions, and file size.
  • FIPS: FIPS 140-2, U.S. Federal Information Processing Standards 140-2.
  • Wipe technology: Toshiba's unique technology which automatically erases data when a drive is accessed by an unregistered system.
  • "2.5-inch" and "3.5-inch" mean the form factor of HDDs or SSDs. They do not indicate drive's physical size.
