Great disk for CCTV NVR
Excellent Hard Drive that I have added in to a NVR. Disk was detected straight away and formatted perfectly. This operates perfectly fine for multiple 4k feeds so speed wise does the job. I've only had it installed for a matter of weeks so cannot determine how resilient it is.

A very good and reliable hard drive for CCTV.
I bought this to replace an identical one that I bought about 10 years ago. I use them for multi camera CCTV that records AHD 24/7. 8TB stores 8 channels for around 4 weeks before overwriting the files. Comes very well packed and is a simple 'plug, format and play'. Delivery was quicker than expected. All good.

Very quite & smooth playback
I've had the drive in my Klear Pro Max NVR now for a couple of weeks, runs very quiet smooth playback. Obviously at this point don't know how the long term will be, but so far so good

Working fine, just a little noisy
Arrived on time, and I've installed it into my UDMSE without any issues. However, it's noisier than I expected. Apparently, this is typical with larger disk drives
