Been finding some good deals on 2.5 disks lately, but have never bought one before. Have a couple of 3.5 disks on the other hand in my Unraid server. Wondering how much it matters wether I get a 2.5 or not? What form factor do you prefer/usually go for?
Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I’ve seen in this thread:

Depends on your NAS server. If you’re like me and using an old optiplex, you can fit WAY more 2.5" drives in it, and they’re pretty cheap. If you have an actual proper server chassis, then you probably want 3.5" NAS hard drives cuz warranty and all that.
Power-consumption.
Also, the vibration produced by the 2.5" drives is less, but they’re more-sensitive to it, to begin with.
I’d not even consider spinning-platter drives, nowadays, though:
SATA SSD’s for a NAS strike me as being the sanest choice.
Samsung what are those called, Evo drives?
excellently-high MTBF, ultra-short ( compared with rotating-platters ) seek-time ( literally orders-of-magnitude quicker ), etc.
I don’t know of ANY reason to go with spinning-platters, nowadays.
( & I’m saying that as a guy stupid-enough to have not realized this in time, & who spent money on such a thing, when SSD’s really were the answer )

Price per terabyte is lower on HDDs. For bulk storage they are currently the best path. SSDs are catching up though, and there are cases where a SSD based NAS does make sense. But most folks at home don’t have the network capability to fully utilize their speed. Network becomes the bottleneck.
