Each replica is 8192 512-byte blocks and there are two per device.

I usually create a 64MB slice 7 for the replicas.

If you just want to mirror two disks make them as small as possible (one
cylinder). My mddb has a total used size of ~48kB with 6 objects in it:

# metastat -p
d2 -m d21 d22 0
d21 1 1 c1d0s1
d22 1 1 c2d0s1
d1 -m d12 d11 1
d12 1 1 c2d0s0
d11 1 1 c1d0s0

So with ~8KB per metadevice a mddb of 1MB is able to fit 128 objects in it.
