one of the later operating systems to configure<br />

the drive. It will also be necessary to ensure that<br />

the latest firmware is installed in the target device<br />

for any manufacturer that supports such high<br />

capacity drives in their recorders.<br />

With a Windows or Linux based system the<br />

drive can be GPT initialised and a simple volume<br />

created that results in an impressive<br />

13,999,884,984,320 bytes of free space though<br />

this reports as 12.7 TB due to the base 2 method<br />

of calculation on Windows machines.<br />

Health Management<br />

In addition to standard SMART (Self-Monitoring,<br />

Analysis and Reporting Technology), the drive<br />

includes a range of software routines to monitor<br />

its performance and operational status. This<br />

monitoring is said to cover over 200 factors<br />

including such things as temperature, error logs<br />

and vibration statistics and to recommend<br />

preventive actions.<br />

The “SkyHawk Health Monitoring” is<br />

currently incorporated into selected NVRs<br />

produced by Hikvision, Dahua, Tiandy and Uniview.<br />

This allows preventive measures and interventions<br />

to be undertaken if anomalies are detected.<br />

Replacement and recovery service<br />

gives a potential for charging<br />

customers a regular fee to provide<br />

replacements and to return<br />

recovered data<br />

Recovery Service<br />

Seagate have taken a “Prevention – Intervention –<br />

Recovery” approach. With a robust data recording<br />

process, notification of potential for failure and<br />

finally a data recovery service that can provide an<br />

advance replacement drive while the suspect<br />

drive is returned to the manufacturer for analysis<br />

and data recovery.<br />

This replacement and recovery service gives a<br />

potential for charging customers a regular fee to<br />

provide such replacements and to return<br />

recovered data if a suitable support agreement is<br />

in place.<br />

Performance<br />

The drive runs relatively cool with a case<br />

temperature of around 33°C when not enclosed.<br />

The operating range is stated as 5°C to 70°C<br />

though this is “drive reported temperature” not<br />

ambient. The reported temperature matched the<br />

measured case temperature during the tests.<br />

In testing the drive reported a Write rate of just<br />

under 260 MB/s just above its specified 250MB/s<br />

and a Read rate just above 260MB/s. The<br />

maximum Read and Write speeds were achieved<br />

at the outer sections of the drive as expected with<br />

a reduction for the inner tracks due to relative<br />

speed and track length. In all cases the average<br />

for the drive was above 200MB/s. This<br />

performance was compared to a standard 1TB<br />

7200 rpm desktop PC drive that achieved a<br />

maximum 148 MB/s time and a 2TB 5200 rpm<br />

desktop drive that achieved just 62MB/s.<br />

Conclusion<br />

A very fast and efficient hard drive with an<br />

impressive specification, vast storage and<br />

manufacturer support for data recovery if<br />

required. The attention to the specific current and<br />

developing requirements of the surveillance<br />

industry should ensure that this drive provides<br />

the required performance and longevity of<br />

service.<br />

9.0 out of 10<br />
