Implications of changing MemCached maximum block size

Question

What (if any) are the downsides of running MemCached with say 100MB maximum cache block sizes?

Would it run any significantly different to using 10MB or 1MB pages? Reversely, why would you run MemCached with smaller pages such as 100k?

If MemCached was set to use 100MB maximum size, would it actually allocate 100MB for every memory unit regardless of how big it actually was?
