We use Utimaco disk encryption for whole disk and we've never ran into
any production issues. We are a smaller office, but we've also done
large deployments which have similar experiences. Law enforcement is a
huge fan of this technology. We use hardware tokens with certificates
for authentication.

Brad is right, it really is the way to go, sensitive data is stored
all over the disk in many cases. Whole disk encryption solves the
problem.
