I'm not convinced that you are collecting enough information to get
useful statistics, in particular, you lack any data about drives that
haven't failed yet.
Suppose that there are two vendors sell drives with identical
characteristics, one of which sells twice as many drives as the
other. In your statistics, you will give the appearance that the more
popular drive performs less well because you see twice as many
failures.
A better approach would be for people to register their drives with
you when they are new, and then to inform you when the drive fails or
is otherwise disposed of. The problem here would be to keep track of
the drives to ensure that failures really do get logged.
