[Bio-Linux] Fresh install - partitioning?

[Raony Guimaraes Corrêa Do Carmo Lisboa Cardenas]

You are not the first person who says about btrfs Tony. Thank you, I will
definitely give a try on the next few weeks on this.

I will also benchmark read/write speeds with 4 disks in raid 10 against 2
disks in raid 0.

I will leave my /swap in ext4 for now since I barely used it.

Kind regards!
