Yes, laptop spindle drives are designed for light duty. They are intended
for a laptop and typical laptop usage patterns. If you tell a drive mfgr
you're using laptop drives in a server, they will almost assuredly tell
you that will render your warranty null and void.
I used to work at Seagate, while I was still designing hardware. And I
can tell you spindle drives are immensely complex machines. It is
nothing short of amazing how cheap they are, and that they even work at
all. We all just take them for granted, but the technology in those little
cases is quite advanced. And the design methodologies are fully tuned for
the effects of usage patterns. The drive mfgrs are designing drives to
live until the warranty expires, based on a typical usage pattern. Change
the usage pattern, and you are flying without a net.
