I got this as an expansion addition to my Asustor Lockerstor AS6706T (6 bay, 4 occupied, 2 left for spare install.) So far it works pretty well!!! This model is the newest one that Asustor currently offers at the time of this review. The only thing I didn’t initially like is the styling…the front cover panel is an angular magnetic snap on panel which really doesn’t match the styling of the main unit AS6706T. Other than that the performance seems quite good as it interfaces with the main unit via a USB 3 connection. I have it configured as BTRFS RAID 5 format which allows 1 disk failure before replacement and rebuild and also allows snapshots which if a file gets deleted I can revert to an earlier date version for recovery. I’m trying to mostly use this volume as a zipped files directory backup for somewhat archival purposes–fingers crossed it will do what I need it to do!!! My main unit I have WD NAS REDs and this unit I have WD Desktop Blues–trying to separate/segregate the drive types per box so I can see how each performs. So far I am able to direct stream with PlexServer/PlexAmp with no issues other than slow network connections. Just a note that setup was decently easy using the ADM Software provided through the Asustor NAS management web portal.
