Can I run Windows' defrag on an SSD drive ?

Why can't you defragment Solid State Drives?

Is defragging relevant to improving disk performance anymore?
Does it stil make much difference, now that we have much faster and larger HDDs? Generally I find if disk performance is getting too slow, it's probably because of too little free space, and the solution is to buy a new HDD.

Should I defrag the hard drive running on a Virtual Machine?
