BUILD Mirror performance question

[JuliusMaximus]

I am working on building a NAS primarily for streaming 3-4 devices but also as an extra form of backup.

1. Will mirroring 2 4TB drives perform well enough for these tasks?

Here is what I am thinking for the build:

Supermicro MBD-X10SLL-F-O
i3-4170 3M Haswell Dual-Core 3.7 GHz
Crucial 16GB (2 x 8GB) 240-Pin DDR3 SDRAM ECC Unbuffered DDR3 1600 (PC3 12800) Server Memory Model CT2KIT102472BD160B
2x WD Red 4TB NAS Desktop Hard Disk Drive - Intellipower SATA 6Gb/s 64MB Cache 3.5 Inch - WD40EFRX

By streaming 3-4 devices do you mean simultaneous transcode to 4 devices? Some devices support direct play so there will be no transcoding and some will do direct stream (partial transcode) if the container file has an unsupported audio/video file type. The i3 you have listed should be fine and zfs will give you more performance then what your disks are rated for through the ARC. If it is slow or stutters add more ram.

Most of the devices probably won't require transcoding. However I would like to support transcoding in the future if I decide to run plex which I am assuming requires transcoding. Currently I use 3 Raspberry Pi's and a small asus all running openelec
