I have a small office server that I use with Ubuntu 16.04 LTS. I tried using the fakeraid on the motherboard but it only gives me about 750 GB total space and I have 2x3TB drives. My idea is to configure them using RAID1 but of course I would need a RAID controller to exploit the benefits. The thing is that I haven't seen a regular-priced RAID card that shows Linux compatibility (Ubuntu certified RAID cards section). ($50-$80 USD range)
I kinda like this one for its specs and features and it seems to have good reviews. There's a person mentioning that it's compatible with 12.04 so my best guess is it should be compatible with 16.04.
The thing is that I can't seem to find info on whether it's compatible or not, whether it would support 2x3TB drives (some cards say they have memory limit).
Has any of you guys tried something similar?
