New 2.5-inch HDDs in capacities up to 600GB with optional self-encryption features
TOKYO—Toshiba Corporation (TOKYO: 6502) today announced new additions to its lineup of enterprise performance hard disk drives (HDD), the AL13SXB series and the self-encrypting AL13SXQ series, which are suitable for mission-critical enterprise applications. Sample shipping will start from the middle of March.
The AL13SX series offers capacities up to 600GB, the largest-class storage capacity in a 15,000 RPM 2.5-inch design, double the maximum capacity of previous generation drives. The drives provide lower latency and power savings compared with legacy 3.5-inch 15,000 RPM 600GB models.
Customers have the choice of AL13SX drives that support 512n(native), 512e(emulation) or 4Kn storage formats. The long sector models (512e and 4Kn) reach sustained transfer rates up to 243 MiB/s – an increase of 27% compared to previous generation drives. The 512n models provide an increase of 19%, with sustained transfer rates reaching 228 MiB/s.
Customers also can select a Sanitize Devise Feature set function, which makes it possible to quickly invalidate data recorded on the magnetic disks.
The long sector models provide persistent write cache technologies that help protect against data-loss in the event of sudden power loss.

 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.

 Toshiba Semiconductor & Storage Products Company defines halogen-free and antimony-free hard disk drive 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.
 Toshiba Semiconductor & Storage Products Company defines "RoHS Directive" as the 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.
