Tony,

Nimble SSD is used for "hot active reads".  I am assuming that your snapshots are older and all the data is not accessed all the time.  So when we go to remove the VMware snapshots that data is being remove from data not on SSD.  It will not affect your performance it just make the numbers look less because the data you are removing is old data and you are not using that data anyways so no effect.
