Enterprise Performance HDD

AL13SXBxx0N Series

The AL13SX series Enterprise Performance 15k HDD models combine the performance of 15,000 rpm spindle speed with capacities up to 600 GB in a compact, power efficient 2.5-inch form factor. The series is meticulously engineered for mission critical IT operations. The AL13SXBxxxN supports 6.0 Gbit/s SAS interface and provides 512 B per sector native format required for legacy applications and operating environments while delivering sustained transfer rates reaching 228 MB/s. In addition, the AL13SX series helps to reduce operating costs by lower access time and power savings compared with Toshiba legacy 3.5-inch 15,000 rpm models (MBA3xxxRC).

  • 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 a function 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.
