AFAIK they have to be of equal size but as you can create a 27GB partition on 
the 40GB drive, you could at least get 54GB out of this configuration. 

I have never used it but I think that LVM can also do just that: Concatenate 
multiple physical disks to one big logical.

If one disk is a lot slower than the other it could happen that the RAID0 is 
slower than the single disk.
