Dose the ReadyNAS NV+ v2's single core CPU powerful enough for 4K Vedio streaming?

One warning here - a lot of NV+ v1 owners mistakenly think they have a v2.  The labels are a bit confusing.

An NV+ v1

• runs 4.1.x firmware
• says NV+ on the front panel
• might say v2 or v3 on the label on the bottom or back.
• uses a sparc CPU

An NV+ v2

• runs 5.3.x firmware
• says NV+ v2 on the front chassis
• uses an arm CPU

Netgear stopping shipping the NV+ v1 in 2011; they stopped shipping the NV+ v2 in 2013.

Both models use SMB 1.0, so if you are running Windows 10 you will need to make sure the SMB 1.0 client is installed on the PCs.

4K streaming rates (from Netflix or Amazon) are about 15-25 mbps (2-3 MB/sec).  4K BluRay is no more than 128 mbps (16 MB/sec).  An NV+ v2 can deliver about 60 MB/sec, so it can easily stream 4K.  

However, the NV+ v2 can't transcode in real time (and new ReadyNAS can't transcode 4K in real-time either).  So your players will need to support the formats  - generally HEVC for video, and dts, dolby digital (ac3), or aac (mp4) for audio.  Plus your network will need to carry the traffic - not difficult for gigabit ethernet, but the BluRay rates could be a challenge for your wifi.

Also your options for the streaming server are limited.  In particular, Plex stopped support for the NV+ v2 some years ago.

Although I've never owned an NV+ v2, in my opinion the software never became fully mature.  So you should review the software manual, and make sure it has what you need.  http://www.downloads.netgear.com/files/GDC/READYNAS%20ARM-PLATFORM%20(DUO%20V2,%20NV+%20V2)/RAIDiator%205.3%20SW%20Manual_5Sep12.pdf
