The HGST Deskstar NAS is one of the few NAS drives to feature a 7,200 RPM rotational speed. This relatively high rotational speed helps the 4TB Deskstar NAS achieve a 4k read/write speed of 1.14/2.2 MB/s. 1.14 MB/s is actually the highest 4K read speed I have seen to date on a 4TB drive. In terms of sequential read/write speeds the Deskstar NAS clocked in at 161/144 MB/s which are also a reasonable set of scores. Overall the Deskstar NAS scored an effective speed of 116 MB/s which despite being 14% below the group leaders, is still second place for a 4TB capacity drive. With 4TB of capacity and an above average performance profile the HGST Deskstar NAS represents very good value for money. [Mar '14 HDrivePro]
