Re: Possible to bring in data stored on S3?

Itís quite fast. Using the AWS CLI tools, I clock downloads at ~180-200 MB/s (megabytes per second) from S3 to an r3 instance. Similar for uploads. The CLI tools run up to 10 threads per download, thus the speed. YMMV of course, especially with smaller instances. Keep in mind S3 does not provide real random access (though byte-range headers are supported), so it cannot replace NFS/EBS in all cases.
