just remember 3.5" drives, particularly the higher perfomance/enterprise drives 
can require well thought out cooling, this is a primary reason you just don't 
see 10k drives in desktops any more (had one in a mac, factory in 2001), in 
most machines they'll fail in months, they just need more cooling than most 
cases provide or can provide.  i have a slower 3 tera hgst(7500/7800 or there 
abouts) (now made by one of my least favorite vendor who bought the tech from 
hitachi) and in my warm apartement (health problems, it hurts less when it's 
very warm) have mild difficulty keeping it bellow 100 deg F.  the drive is in a 
cage directly behind a fan mounted to the front.  if you take old machines 
apart you'll notice some vendors putting the drive right behind a grill on the 
front, positioned vertically to expose maximum area to air flow, these are 
slower drives but still benefit from more cooling than is "traditional", i.e. 
unchanged since the 90's.

External cases rarely have significant cooling (even those with fans), the old 
usb2 externals will all cook your' drive rapidly if you do large datatransfers, 
they are only passable if doing small writes, like backing up single files, not 
large portions of another drive (or restoring either).  The "advantage" of 
laptop drives, and the reason they have become popular in servers is that they 
are designed to be low power, and to function in a difficult thermal enviroment 
(it's hard to cool a laptop).  they dissipate less power per byte stored, and 
are of course slower which may or may not matter particularly in a raid setup 
or if most of you're drives can spin down most of the time, they also usually 
pause them selves at a preset temperature until they cool down and constantly 
park.  if you boot off a laptop drive it will take a long time, or if you try 
to move lots of files.  for archiving media it's probably not a problem, for 
development work or engineering use it may drive you nuts and waste you're 
time. 

 if you're going with external drives use laptop drives, or build a JBOD with 
good cooling.  in any case, monitor drive temperatures, in my experiance 
anything above 100F is asking for a short life, bellow or at 100F drives new 
and old are happy for over a decade which seems like a long time, but most of 
us have data on older machines with older drives somewhere in the house and 
most don't back that up or back it up often enough.  also note that most usb 
adapters don't even allow smart access, so the only way to see if the drive's 
hot is to feel the enclosure which is not terribly accurate or usefull.  it's 
also really nice to be able to run smart diagnostics and have the os monitor 
the smart status which most versions of linux will do, don't know about 
winblows, haven't run that since xp.
