Default mode of drbd operation is synchronous as you mention and its
performance is purely dependant of underlying block device. Having a gig of
battery backed write cache on each side helps :)
Asynchronous mode of operation is actually a special case for drbd and is
primarily meant for geographically distributed setups that replicate data
over wan.

But as the opening poster said he has a small number of users, drbd with
standard sata disks should be fast enough.
