## Planning Your Large Transfer

* **Note**\
  For large data transfers, we recommend using the Amazon S3 adapter to transfer your data.
* **Note**\
  Metadata operations are performed for each file that's transferred. Regardless of a file's size, this overhead remains the same. Therefore, you get faster performance by compressing small files into a larger bundle, batching your files, or transferring larger individual files.
