It definitely fits one big hard drive or several small ones. It's a lot bigger than expected but definitely protects the contents inside. The only drawback: After unpacking, it smelled very strongly of chemicals. The smell was so bad for me that I had to leave it outside hoping to air it out. If the smell doesn't go away I guess I'll have to send it back. already a problem.
