Rasberry Pi 3 and NAS ?

[Bradl79]

I am looking at getting a Mediasonic HFR2-SU3S2 PRORAID 4 with 3x 3TB drives in Raid5 and a Rasberry Pi 3 model B and use it as a personal NAS for my Movie Collection (1080p and 4K mkv files) do u think the Pi would be able to handle that? thank you, also too i have never done a raid5, will i still get the combined speed of the 2x 3TB drives as i would in Raid0?

No, the Pi will struggle with 1080p transcoding and definitely will not be able to handle any 4K transcoding. The RPI3 as far as I can recall only has a 100Mbps interface as well so you will saturate that long before you hit the limits of the read/write speeds of the disk. As for RAID 5 speeds you won't get near the same speed you would if you did RAID 0, you might get like 1.5x the speed of a single drive.

If you're just using the RPI3 as a file server then it'll do fine but I would recommend getting another drive and going for RAID 10 instead, it'll be much faster and more reliable but you are still limited to 5Gbps over the USB3 on the storage device, not to mention the RPI3 only has USB 2.0 ports which will limit it even more.

Raid 5 will be faster for this use. Raid 5 normally has faster sequential reads and writes. 

 

For op, just get a basic nas like a synology. The 100mbit port on the picture is slow and it's all running on the same USB bus.

I don't think it would be a smooth experience. As the people above mentioned, the Pi only has a 100Mbps Ethernet port, and it doesn't have any USB 3.0 ports. Even if your drives were in raid 10, they wouldn't be used to their full potential because of all the bottlenecks.

do it as a file server i have a pi 2 nas love mine. use this http://www.techradar.com/how-to/computing/how-to-build-your-own-raspberry-pi-nas-1315968

There are much better options out there, the RPi just doesn't have the performance.

Thank u for all of the info everyone,  I think i may be better off spending extra money and getting a Buffalo Linkstation

Get a separate NAS and use the Pi for watching video. I've watched a lot of 1080p on mine and it works flawless but 4K is no option I think.

You'll have a pretty rough experience with the Pi.
