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 )
I lament Nova’s demise, too…
I think the reason that the tech companies won’t allow us to have our devices our own way ( Microsoft was doing this decades ago ), is “religious”/ideological, not practical:
I think they “need” to keep everybody permanently in a headlock, with our heads all twisted, because only if we are all in permanent learned-helplessness, only then can they automatically get away with everything they intend to be getting away with, in our world.
IOW, our autonomy violates their totalitarian religion, see?
It’s the same as how ANY spirituality grates on Dawkins’ blood: he wants it all gutted/butchered/destroyed, & suicides of ones he destroyed are no problem for him, & no alternative ever can have any validity to him.
Totalitarianism, whether traditionally “religious”, or in any other ideology/prejudice/religion, is the same: it HATES violation of its homogenous dominion.
( comically: homophobic-religions want a homogenous het humankind, with no violation of that homogeneity. The existence of homosexuals is too heterogenous for them )
Autonomy is something that totalitarian supremacism ideology “needs” to obliterate from the whole world.
Consistently.
It seems to be a damn-good diagnostic for it, even!
