This is a Storage icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,700 icons, all in the same style and quality.
The icon is a logo for storage. The icon is circular in shape, and has 2 dashes on the edge of the circle. The first dash is located in the 12 o clock position, the second dash is in the 5 o clock position.
