This Network Drive icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,600 icons, all in the same style and quality.
It's a logo of Network Drive reduced to an image of a cloud overhead of a drive. It is a drive that can be used to store information over the internet instead of on a hard drive. It looks like the network drive logo on my computer.
