Sandy is the name of the energetic squirrel in "SpongeBob Squarepants." I don't think Sandy, in this case, is associated with the names Alexandra or Sandra. She is named that because of her color and because she's a "land squirrel." An actress who bears this name is Sandy Duncan.
A correction - or rather, addition - to a previous comment: Sandy Cheeks from SpongeBob's real name IS Sandra, but I do think it also is a reference to her fur. :D

In the Time Quartet series of books by Madeline L'Engle, Sandy Murry is the twin brother of Dennis Murry. He is also the brother of Charles Wallace Murry and Meg Murry. In A Wrinkle in Time, he doesn't appear too much, but Many Waters features his twin and him very prominantly as main characters.
I can't really see this name on guys anymore, it sounds very feminine and cutesy. It's a nice nickname for Sandra, which sounds a tad harsh, whereas this name has a soft sound to it. My associations to this name are quite negative, though. The name sounds like a mean high school girl name from the 90s, and the series Daria with its mean and manipulative character Sandy Griffin probably has a lot to do with that. On the other hand, it sounds like the name of someone a bit bubbly and ditzy.
Awful name. Anything that ends in "dy" is ugly. Andy, Mindy, Mandy, Candy. Gross. As a prostitute's alias - ok, as a first name - not ok at all. Even uglier when "y" is swapped with "i".

Sweet, gentle name. Prefer it spelled "Sandie" for a girl or woman.
Much prefer it as a boys name and the majority of people I know with this name are male, and the only girl I know spells it Sandi.

Hurricane Sandy, also known as Superstorm Sandy, was a large hurricane that hit the Northeast United States in October 2012. At the time I posted this comment, it was the largest U.S. hurricane on record.
