Another great product from Ubiquiti. User friendly installation and configuration. From inital testing using a SSD cache this product is very fast. The real test will come when having to replace failed hard drives or expanding the array. Only word of caution is that the SSD caddys are NOT INCLUDED with the NAS (when all other rack mounted NAS' I used come with all parts needed). While this was done to only pay for what you will use I thought the $55 cost was a bit steep for the caddy.
