title: Is varchar(128) better than varchar(100)
body: <p>Quick question. Does it matter from the point of storing data if I will use decimal field limits or hexadecimal (say 16,32,64 instead of 10,20,50)?</p>
  
  <p>I ask because I wonder if this will have anything to do with clusters on HDD?</p>
  
  <p>Thanks!</p>
