Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I want to setup a small application server running 12.04, mostly running bioinformatics tools. The box has 16GB of RAM and 12 core and 6x2TB SATA disks.

I need a system partition of, sat at least 1TB, and a data partition of the rest. Read speed is more important than write speed, but this is primarily a calculation server, so neither is of the utmost importance.

What would be a good RAID setup? (I'm planning on using mdadm).

My initial idea was 2x2TB in RAID 1 for the system partition, and 4xTB in RAID 10 for the data partition.
