RELIABILITY

[1] Definition of capacity: Toshiba defines 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 1T B = 2
40
= 1 099 511 627 776 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] "3.5-inch" mean the form factor of HDDs. They do not indicate drive's physical size.
[3] Workload is defined as the amount of data written, read or verifie d by commands from host system.
[4] The maximum sustained data rate and interface speed may be restricted to the response speed of host system and by transmission characteristics.
1 Gbit/s = 1 000 000 000 bit/s. 1 MiB/s = 1 048 576 B/s
[5] A mebibyte (MiB) means 2
20
, or 1 048 576 bytes.
[6] Input voltages are specified at the HDD connector side, during HDD ready state.
[7] Make sure the value is not less than DC -0.3 V DC (less than – 0.6 V, 0.1 ms) when turning on or off the power.

[8] The measuring method is based on ISO 7779.
[9] Vibration applied to the HDD is measured at near the mounting screw hole on the frame as much as possible.
[10] At random seek write/read and default on retry setting with log sweep vibration.
[11] At power-off state after installation
[12] MTTF (Mean Time to Failure) of the HDDs during its life time is 2 000 000 hours and AFR (Annualized Failure Rate) is 0.44 %. (POH: 8760 hours per one year (24
hours per one day, 7 days per one week). Average HDA surface temperature:40°C or less, workloads: 550 TB/year, which is defined as the amount of data written,
read or verified by commands from host system). Continual or sustained operation at case HDA surface temperature above 40°C may degrade product reliability.
