Using ZFS with Embedded Linux

I'm running embedded Linux (Debian on ARM/X86_64). Since it is very much like a full OS, with some hardware differential and a different platform, you may consider it as a regular machine. So, this will be used in the robotics field where the computer will ALWAYS be hard reset by turning off power. It would disqualify me to use a UPS so I would need to make the system infallible.

I'm running some processor-intensive tasks, like OpenCV and OpenNI and OpenKinect. How do I use an uber-powerful filesystem, like ZFS to mirror the entire disk on the SSD for error correction? Does ZFS perform well in Linux? I'm still kinda a newbie in Linux so I don't understand it's internal workings.

My list of possible platforms are: --Debian@RaspberryPi --kUbuntu@ODROID-X2 --Ubuntu@PandaBoard --Ubuntu@NUC-i3/5.

Also, how can I make sure the filesystem doesn't get damaged during reset? I need the computer to start in good time, A.K.A, <3 minutes for the competition.

I will probably be using a 32GB SSD, so I guess a 16GB partition mirrored 2x works or 12 @ 3x. I only need to get an OpenCV install working because the code will be downloaded from a SAMBA NFS automatically!

Thanks for your help and good luck ;)!

ZFS is not suited for low memory systems. It do perform well on system with 4GB of RAM and more.
