2.5" CCTV Drives?


Could anyone recommend 2.5" HDD to be used in a CCTV situation.
I am hard locked in using a 2.5" for a certain NVR Product.

2TB would be great…and it would be constantly recorded to not just motion with up to 8x 5MP Cameras.

is this possible?

Generally i would use 3.5" WD Purples, but there doesn’t appear to be a solution for 2.5" (Maybe using WD Black? but they are only 1TB)

Lets say i had to settle for 1TB only, would a WD RED be ok for 24/7 use?
