Synology DiskStation DS920+ 4-bay NAS Review

The AES-NI hardware encryption engine in the DS920+ does a very good job of negating the effects of dealing with data encrypted transfers. In a RAID 5 array there’s only just under 12MB/s drop in performance when writing to the DS920+ and just 10MB/s are dropped when reading the data back.

In RAID 6 the write performance drops 13MB/s while read performance drops 10MB/s.
