5.0 out of 5 stars YES...16GB Works! Smooth Operation...
Reviewed in the United States on 25 August 2017
24AUG2017: I wanted to write this review as fast as possible to let fellow IT (and customers) know that for a FACT it takes 16GB of RAM for upgrade, not the 8GB it states is MAX (Screenshots Provided). I bought the 16GB combo here on Amazon (2x8) (Timetec Hynix h_t_t_p://a.co/cU3Q0Yw) for $92.99. Slapped it with 2 lower 3TB (Seagate 3TB BarraCuda SATA 6Gb/s 64MB (ST3000DM008) drives (was going to go 4TB or 6TB pair...but wanted to really know if QNAP device was worth it...my first one).

I will begin to use it and see how well it performs. But for now, after maybe a 2 to 3 minute boot...the sucker goes fairly fast on clicks to interface (via web browser). Updated firmware to 4.3.3 which up to this date is the latest from July 27, 2017. I will update after I have really played with it.

TIP: Would be wise to update Firmware BEFORE setting device up...Download the Firmware file then use the QFinder Pro software (both things at the QNAP Support Website) to update Firmware from the "Tools > Update Firmware" menu. Then Setup the device...so you use all the latest/updated options.
