For our Backup / Restore test we transferred a 118GB Windows 10 backup folder to and from the NAS.
In our backup/restiore test the NASync DXP4800Plus averaged 297MB/s backing up the data using a 10GbE connection and averaged 347MB/s reading the data back. Using a 2.5GbE connection the NAS averaged 230MB/s for writes and 257MB/s for reads. Oddly the DXP4800Plus seems to struggle in this test at both connection speeds when the drives are built into a RAID 10 array.
