Pros: This is my second QNAP. My main NAS is a QNAP TS-459 Pro + which I have had for a few years. It backs up automatically to my new TS-251. I upgraded the TS-251 with 8 GB of GSkill memory (details in other thoughts) and run the TS-251 as a NAS and Media Server through Kodi. The TS-251 was far cheaper but boots faster than my older QNAP. Transfer speeds are excellent between the two systems. There is never a lag when watching movies. The QNAP web interface takes some getting used to but is very logically laid out.

Cons: Not really a con but this QNAP has two bays. I am running the TS-251 with two 3 TB in RAID 0 so if one drive fails all data is lost. I am OK with this as I depend on my TS-459 which is in RAID5 as my main storage.

Overall Review: Based on recommendations from other posts I upgraded the memory to 8 GM. The maximum memory is 8 GB although I have read others have gone up to 16 GB. The QNAP operating system is very efficient and with 8 GB the system at idle is using 9%. Memory I used: G.SKILL Ripjaws Series 8GB (2 x 4GB) 204-Pin DDR3 SO-DIMM DDR3L 1600 (PC3L 12800) Laptop Memory Model F3-1600C11D-8GRSL

Pros: 63" was big enough to put two large monitors on it. Nice real estate.

Cons: it is a little wobbly.

Overall Review: Great desk at a great price. I recommend.

Pros: This is a great performer. It connets quickly after log in to Windows XP and Windows 7. Did not test with Linux. Good response. Well made. Batteries last about 3+ months.

Cons: None

Overall Review: Connections with Bluetooth seem to be made after the windows login process so it will not connect as early as a normal usb mouse.
