I want a low-power, small, silent x86_64 Ubuntu computer with storage that's resilient against hardware failure of a drive.
I'm thinking of buying D54250WYKH or D34010WYKH, one mSATA SSD and one 2.5" SSD of the same capacity.
With Ubuntu 14.04, can I set up encrypted mirroring RAID across the mSATA drive and the 2.5" drive? Will TRIM work in that case? Will the answer to the TRIM question depend on whether it is some kind of Intel firmware RAID (is that available across mSATA and the 2.5" slot on NUCs?) or an Ubuntu/LVM software setup?
