TB hard drives are available for the desktop and it's getting hard to remember what the order of the SI prefixes being used are. It occurs to me that I really have no idea what kid of scale is considered how big. I'm looking for a yardstick to compare them to. So, what is a really huge DB now days? What is the best measure; GB of data? millions of rows? thousands of queries per second?
Also what about just regular old huge? Big? Mid-sized? Small?
