Less noise- they hardly even make noise, and if your that much of a noise whore get a P180, or something with a tight cage to keep them from vibrating.
Lower Power-wtf 1 normal 7,200 hardrive takes up like 20 watts..
Well, heat is an issue. fan placement will indeed help cooling, but it still does not deal with the fact that a 2.5" notebook drive is something like 1/6th the volume of the 3.5" desktop drives, and let's just say that they are running at the same temperature inside the case. the 2.5" drive has physically less volume, mass, surface area, etc, which will all affect the heat dissapation and also, just the total amount of heat it gives off.
the noise factor, i agree, isn't all that much different, but when you add those fans into the equation, sure you could have 1 or 2 fans blowing on an array of 3.5" drives, but that will make more noise. a lot of 2.5" drives don't really need to be actively cooled unless there are a good amount of them, and even then, you probably need fewer fans per amount of drives.
finally, for power consumption, just based on 2 somewhat random sources (i went to thg since i knew it would be there, and the other just came up on google), notebook drives use significantly less power, most likely because they are just physically smaller.http://www23.tomshardware.com/storag...=414&chart=157http://www.digit-life.com/articles2/.../hddpower.html
on thg, you find the max power consumption is in the range of about 4W. on that other site, going about 3/4 down the page (since most people, i think, use both the 12V and 5V), you find that the idle power consumption of desktop drives is in the 6W range.
