[1] Read and write speed may vary depending on the host device, read and write conditions, and file size.
[2] Definition of capacity: We define 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.
[3] "2.5-inch" describes the form factor of HDDs. They do not indicate drive's physical size.
[4] Sanitize Instant Erase. SIE is a function to invalidate the data recorded on the magnetic disks at a blink.
[5] 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.
[6] Input voltages are specified at the HDD connector side, during HDD ready state.
[7] Make sure the value is not less than -0.3V DC (less than -0.6V, 0.1ms) when turning on or off the power.
[8] Power supply at nominal voltage ±1%. 25°C ambient. Refer to Subsection 2.5 "Power conditions" of the SAS INTERFACE SPECIFICATION for details of idle and
ready states. "Ready state" corresponds to 2.5.2 "Active state" of the SAS INTERFACE SPECIFICATION.
[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) 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.
