  • Read and write speed may vary depending on the host device, read and write conditions, and file size.
  • MTTF / MTBF (Mean Time to Failure / Mean Time Between Failures) of the HDDs during its life time is 1 million hours. This assumes power-on hours are 2400 h/year (average HDA surface temperature:40°C or less, workloads:55TB/year). Use at case HDA surface temperature above 40°C may degrade product reliability and reduce warranty period.
  • "3.5-inch" means the form factor of HDDs. They do not indicate drive's physical size.
