myarray[offset] is simply pointer lookup. All accessors on memoryblocks 
are methods; they perform bounds and endian checks. While bounds 
checking is nice (you can't shoot yourself in the foot by writing into 
someone else's memory), the function overhead and all the checks that 
are performed make it slow.
Proportionally, the function overhead and the checks are much more work 
than actually reading or writing the data.
