One Gigabyte (1 GB) means 109 = 1,000,000,000 bytes and One Terabyte (1 TB) means 1012 = 1,000,000,000,000 bytes using powers of 10. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB= 230 = 1,073,741,824 bytes and 1 TB = 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 and other factors.  Actual formatted capacity may vary.

2 Compatibility may vary depending on user's hardware configuration, and operating system.

3 Product specifications, configurations, colors, components and features are subject to change without notice.

4 The maximum sustained data rate and interface speed may be restricted to the response speed of host system and by transmission characteristics. Read and write speed may vary depending on the host device, read and write conditions, and file size.

5 Annual Workload Rating: HDDs keep track of various drive usage such as power on hours, lifetime writes and lifetime reads from the host computer. With this data we calculate an Annualized Workload Rate, under 40 deg. C ambient environments, Annualized Workload Rate = (Lifetime Writes + Lifetime Reads) * (8760 / Lifetime Power On Hours) in case Power On time is 8760h or longer. Otherwise (i.e. Power On time is shorter than 8760h), Annualized Workload Rate = (Lifetime Writes + Lifetime Reads) Each drive is designed to perform up to the Annualized Workload Rate stated, after which the drive may be expected to decline. The Annualized Workload Rate in no way alters the warranty policy for such drive. Workload is defined as the amount of data written, read or verified by commands from host system.

6 Number of surveillance cameras support capability is defined by performance simulation with High Definition cameras at up to 10Mbps rate, depending on the HDD model. 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. Compatibility may vary depending on user’s hardware configuration and operating system. “High

Definition” is calculated assuming Full HD 1080p, 30fps, transfer rate of up to 10Mbps/stream.

7 For "Drive Bays Supported", please contact your Solutions Provider because the compatibility with the host device will vary based on the system.

8 Location of bottom mounting hole is different from product. For more information, please see the following page.

9 Standard limited warranty applies. The warranty brochure can be viewed online at

10 MTTF (Mean Time to Failure) or MTBF (Mean Time Between 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 or MTBF. MTTF (Mean Time to Failure) or MTBF (Mean Time Between Failure) of the HDDs during its life time is 600,000 hours and AFR(Annualized Failure Rate) is 1.46%, or 1.0 million hours and AFR(Annualized Failure Rate) is 0.88%, or 1.2 million hours and AFR (Annualized) Failure Rate) is 0.73%. This assumes power-on hours are 24 x 7 in normal usage (8760 h/year power on hours, up to 180 TB/year or up to 300 TB/year total data transfers, and average HDA surface temperature:40°C or less). Use at case HDA surface temperature above 40°C may degrade product reliability and reduce warranty period.

11 "2.5-inch" and "3.5-inch" mean the form factor of HDDs. They do not indicate drive's physical size.

12 Drive life may vary depending on usage and workload.
