Make sure you pick out the right drive for what you are doing. For example this is for Surveillance. We tested this drive against the desktop version of it, and this one was running at 32% usage with Blue Iris and 6 3MP 1080P cameras vs 100% and crashing on the desktop version of this drive.

Fast drive; great sequential write speeds

none

This drive has run flawlessly for 2 years 24/7 recording 10 cameras. Runs nice and cool. It's not meant as a primary drive. It's specifically designed for surveillance and it excels at it.

Best drives for the DVR/NVR

Easy to install, and working well. The previous HD that broke was the same make - which I didn't know at the time so fingers crossed this one lasts longer than a year. Good value for money.

Performed flawlessly from day one. It is nice to have the reliability of a drive designed for continuous re-writes backed by a solid warranty of 3 years.

Beware of Western Digital. WD is cheating customers, if your HDD fails in warranty and you ask WD for replacement, WD will give you a second hand used/repaired hard disk, by putting a lable as re-certified.

I am happy with this product

At the time of writing, the WD Purple 6TB Surveillance Hard Disk can be found at NewEgg for $256.99 , at Overclockers UK for £214.99 , or through Geizhals starting from €251.04 . One should never compromise when it comes to safety and surveillance falls within that category.

Overall great performance; Great price per GB of storage; WD AllFrame technology; Up to 8 drives; Uo to 32 HD cameras

Mechanical drive: higher noise and power consumption than solid state

Price was the best I could find and the unit was very securely packaged. This unit worked perfectly and was received quickly. This was my first purchase and all I can say is "Great job B&H, you have another loyal customer."

Have only had it for around a month, so cannot comment on longevity, but from time to time it starts making noises (it is always on). They go away once I touch it but I find it a little odd, considering it was designed for 24/7 usage.
