Surveillance HDD

DT02-V Series

Toshiba’s Surveillance HDD DT02-V Series are designed for purpose-built consumer and commercial surveillance video systems supporting up to 32 cameras.  The versatile capacity allows solutions designers to customize the storage capacity that best aligns with image resolution and data retention period requirements.  DT02-V series use an energy-saving 5400rpm design to deliver performance tuned for demanding 24/7, multi-stream surveillance environments.  DT02-V series are designed to be compatible with the wide variety of surveillance platforms available from leading SVR and NVR vendors.

  • Product image may represent a design model.
  • 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 1TB = 240 = 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.
  • 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.
  • "3.5-inch" mean the form factor of HDDs. They do not indicate drive's physical size.
  • Workload is a measure of the data throughput of the year, and it is defined as the amount of data written, read or verified by commands from the host system.
  • Number of surveillance cameras support capability is defined by performance simulation with High Definition cameras at 4Mbit/s rate. Actual results may vary based on various factors, including the types of cameras installed, the system’s hardware and software capabilities, and the video compression technology used, as well as system variables such as resolution, frames per second, and other settings.
