Why? Are 2.5" drives more shock-proof?
In general, they are.
I'm asking because I sometimes exchange
big datasets with people by sending standard 3.5" drives, e. g. from Germany
to Australia and back and had no problems so far. Luck?
That depends on the packaging. I've seen 3.5" disks damaged after
sending them by mail when not properly protected, and - more important
in case of the backup scenario - the disks are damaged easily by
dropping them. A few cm can be enough. One of the reasons why I prefer
tapes. (Although SLR/MLR/QIC cartridges don't like being dropped or
shaken, too, but that can be fixed by retensioning them.)
Especially when handling disks without protective packaking you should
be careful when putting them on a shelf, even.
(From my days as a salesperson: We made the experience that disks that
were delivered in the original box and stored and handled in their
manufacturers plastic cases had much less warranty cases than the ones
that came packed in antistatic bags only. A good reseller will only
transport disks in the manufacturers special packaging, like SeaShell
from Seagate for example.)
Back to backup use: If you need 3.5" disks (for example because of the
available capacity) you should use the ones sold by the manufacturer as
external drives, and not sinply put a disk into a cheap case. And make
sure the storage where you keep hem has a soft ground.
