[1] "3.5-inch" means the form factor of HDDs. They do not indicate drive's physical size.
[2] Definition of capacity: One terabyte (TB) = one trillion bytes, but storage capacity actually available may vary depending on operating environment and formatting.
Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system and/or pre-
installed software applications, or media content. Actual formatted capacity may vary.
[3] MTTF (Mean Time to Failure) of the HDDs during its life time is 600 000 hours and AFR (Annualized Failure Rate) is 0.4 %. (POH: duty of 2400 h/year, average HDA
surface temperature: 40 °C or less, workloads: 55 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.
[4] Read and write speed may vary depending on the host device, read and write conditions, and file size.
[5] A kibibyte (KiB) means 210, or 1024 bytes, a mebibyte (MiB) means 220, or 1 048 576 bytes, and a gibibyte (GiB) means 230, or 1 073 741 824 bytes.
[6] 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
[7] Read–modify-write is supported.
[8] Input voltages are specified at the HDD connector side, during HDD ready state.
[9] Make sure the value is not less than DC -0.3 V (less than -0.6 V, 0.1 ms) when turning on or off the power.
[10] Operating watt is measured using 80% random read/write and 20 % performance idle.
[11] The measuring method is based on ISO 7779.
[12] Operation of high surface temperature will be shortened of the drives useful life. The recommendation operating condition of surface temperature is less than 60℃
[13] Vibration applied to the HDD is measured at near the mounting screw hole on the frame as much as possible.
[14] At random seek write/read and default on retry setting with log sweep vibration.
[15] At power-off state after installation.
