Fit and forget
Dropped this into our CCTV NVR, clicked on format. A few minutes later it was back up and running recording four 4k Video streams. It should give us several weeks of storage. Couldn't be simpler. Only minor criticism is that it is a tiny bit noisier than the old drive but only noticeable when you really listen carefully.

Noisy but works well, so far
Well priced and for backip storage, media disk, it is speedy enough. Quite noisy though. We shall see how long it will last

Great CCTV HDD.
Bought due to a failure with an old Seagate drive. Easy to install. Formatted and worked first time. Already noticed a notable access speed increase vs the old seagate. Very pleased. Installed in an Annke CCTV DVR system.

Toshiba 4TB NVR HDD
The best price for a replacement hdd for my NVR after the old hdd decided to stop working. The 4TB capacity should allow for many days weeks or months of recording before overwriting video depending on how many cameras, the quality chosen and bitrate. Plug and play installation, quiet and seems to run without excessive heat. Perhaps a fan inside the NVR would help as keeping the temps down is always worthwhile.

Does what it says on the tin
Arrived earlier than expected! Bought to replace a Skyhawk drive that went bad - needed a 4tb replacement for cctv - so far seems to be doing the job required. And my cctv is back in action. Not badly priced and good capacity

Very poor quality
I bought two. After they arrived, I went straight to the installation location, which is at my friend's house, at least an hour away. I installed them, but to my surprise, the first one didn't work at all; it had a problem and was very loud. The second one worked at a relatively low volume, but the next morning it was completely out of order. Now I have to go back again to have it reset and returned.
