> 3 dayLasted less than 3 months in a NVR. Reformatting did not help. It constantly returns an error status. As SSDs have come down in price since then (and work perfectly fine in my other NVR), this is probably the last hard drive I will ever buy. SSDs are still more expensive, but that is a trade off I am willing to make. I have had many failed hard drives (usually after a year or more, though), but not a single SSD failure that I can think of. The hard drive was also noisy with constant thumping noises when it was originally working. Noticeable and annoying in a quiet office. It was warm to the touch even when the only thing it was doing was sending a error status back. The SSDs are much nicer to live with.

06-04-2025I was able to replace my failed HD in my UDM Pro with this 6TB WD Purple hard drive. I did not have to do anything special, just install it. I still retrieve my videos as quickly as before.

Greater than one weekI’d purchased a larger capacity drive for my UniFi UDM-Pro, which sits on the top shelf in my TV room. It was speedy, but so loud that there was constant noise over the TV unless at very high volumes. Switching to the WD Purple made that noise vanish instantly and it’s been just as good at recording my doorbell camera. If you need a reliable and above all QUIET hard drive, the Purple line is for you.
