Seagate BarraCuda 2TB SATA based 2.5" Internal Hard Drive with 5400 RPM & 128MB Cache

Works perfect for a OOSSXX dvr system, our original hard drive took a dump and this worked perfectly however they stated the original harddrive was a 2.5" sata hard drive and this was a fraction of the size as the original hard drive bur it worked perfectly, simply plug and play and format the hard drive, and the price was great as well for 2TB, couldnt ask for more

My Unifi Cloud key Gen2 plus came with a 1TB hard drive. After five years of continuous use it was becoming slower and less predictable in connecting to the Unifi Portal.As was somewhat apprehensive about using an SSD as they are more expensive and have a finite read/write capacity.The problem with a larger capacity hard drive is that the 2.5 inch format is limiting. Ideally, one should choose a CMR drive for an NVR. However, the only CMR 2.5 inch drive is the 1TB Toshiba. If you want a larger drive, you end up with an SMR drive. That will decrease the longevity of the drive. As they say, mileage may vary....If only Unifi allowed a 3.5 inch drive, but they don't and there is no workaround other than MacGyvering an external interface.This drive is fast, is essentially plug and play, and is working without a hitch.Just remember to confirm there is a recent backup of the Unifi operating system or you will lose all the camera and other hardware connections.

Thanks to Scott for going above and beyond helping me to make the product in use and to not return it (coz i hate returned items). And now the item is working and running! We’re both problem solver not just “if its not working just return it” guy.Thank you and appreciate all your effort for helping me!- Noel/Dennis
