It's a really good price. I bought a 5tb Toshiba Surveillance HD for $130 in 09/2019

Looking for a WD Purple for a UDM Pro. Worth waiting for a faster drive?

I would. In a single drive setup like you're talking about the performance of a 5,400 RPM drive is going to be more noticeable than in something like a multi-drive array such as what's found in a NAS. There's a reason why Ubiquiti offers this drive but in the eight terabyte 7,200 RPM flavor.

I have this drive in my udm pro. It's perfect for the price and storage size. I notice no lag when pulling up video segments or action items for review.

I'd buy it again as I only run 5 cameras at fhd.

Definitely weigh this first-hand account higher than my post above. I have a UDM Pro currently but have yet to pop for an HDD. When I ordered my UDM Pro I already had a camera setup and a license of Blue Iris software to run it all. I figured I'd eventually upgrade pieces here and there but wasn't in any hurry so I was sure I'd find a better deal on a HDD than the 8TB for $190 they offer. I'm kind of kicking myself as the prices haven't really come down and now I'd like to add a G4 Doorbell and replace my annoying Amcrest one that was the best of the sub-$200 w/o recurring fee options. I was concerned that the smaller drives wouldn't be enough storage and also the 5,400rpm would be a noticeably hit to performance whenever interacting with recordings & such.

You're saying that this drive is perfectly fine for 5 cams running FHD? How much capacity do you use up roughly?

If this drive will meet my needs (probably a doorbell cam and 4-5 external cams for now) I may just grab one now and order up the doorbell cam to get swapped out and running ahead of overhauling the rest of my cam solution.

I am using 4 of these in my unifi unvr. These are the best of the best. For a nvr, you do not need 7200rpm.

Keep in mind that your UNVR reads/writes to multiple drives simultaneously so the individual drive speed isn't as important. The array is much faster than the individual drives contained within and often times the network connection is the bottleneck on something like a NAS or another device (your UNVR for instance) that uses several drives in an array. Something like a UDM Pro has but one drive slot so that means that the rotational speed of the drive is the bottleneck in the chain. His question is a lot more relevant in that device than yours. Another poster above said that the performance is fine w/a single 5,400rpm drive but I'd like to see a side-by-side comparison on something like the UDM Pro to see what the real world experience difference really is.
