I have run some tests transferring from a ReadyNAS 102 to a NTFS formatted USB3 Seagate Expansion HDD (connected to one of the back USB ports).

 

Transferring one large file (3.3GB ISO), speeds were as follows;

 

Using the GUI browser to copy from NAS share and paste to USD UDD: 21.1MB/s

Backup Local NAS Share -> Local USD HDD: 62.48MB/s

Backup Local NAS Share - > Remote RSync(127.0.0.1) USB HDD: 19.9MB/s

Backup Local HAS Share - > Remote Windows Timestamp(127.0.0.1) USB HDD: 14.9MB/s

 

is this consistent with other user's transfer speeds?

Once every 4 weeks I do a full backup of appox. 900 GB of data (mixed files from few kB to 2.5 GB), to a Samsung Portabel USB3 drive (Seagate disc), and the backup completes in just over 3 hours and 15 seconds.

If my calculations are correct that should be somewhere around 77 MB/s.
