# Using data repositories with Amazon File Cache
<a name="using-data-repositories"></a>

Amazon File Cache is a fully managed, high-speed cache on AWS that makes it easier to process file data, regardless of where the data is stored. Your cache serves as a temporary, high-performance storage location for data stored in on-premises file systems, AWS file systems, and Amazon Simple Storage Service (Amazon S3) buckets. Using this capability, you can make dispersed data sets available to file-based applications on AWS with a unified view and at high speeds—sub-millisecond latencies and high throughput.
