Download SRA data with Aspera command line utility
Asperaconnect is NCBI's recommended data transfer client for large datasets >1GB. It uses the FASP protocol, here's a description from the NCBI guide.
"The FASP protocol from Aspera (www.asperasoft.com<http://www.asperasoft.com<UrlBlockedError.aspx>>) uses UDP, eliminating the latency issues seen with TCP, and provides bandwidth up to 1 gigabit per second (Gbps) to transfer data. It has a restart capability if data transfer is interrupted midstream and is well behaved, so if there is other data traffic on your network connections, it will back off in order to avoid starving other protocols. We have seen effective throughput up to 800 megabits per second (Mbps) to a single site.
The fasp protocol uses UDP port 33001-33009 for data transfer and you may need to contact your IT security staff if this port is not open to NCBI through your institutional firewalls.
