The plan here is to build a new machine this weekend and use 2 identical NVME SSD’s in a RAID 0 setup, via mdadm.
But first... two questions:
1. All the advice Google has turned up for me relates to 16.04. Has anything changed in 18.04 regarding software RAID creation and use? Can’t find any Ubuntu docs to say it has, but the RAID docs aren’t all fully current.
2. It’s a UEFI motherboard. If I tell the installer — Ubiquity— to “Use the Entire Disk” AND that disk is the RAID partition, e.g., /dev/md0, will Ubiquity create a swap file as it would during a normal non-RAID install? (I am assuming that swap file will be striped and otherwise treated as any other FILE.)
(Should add I’ll be booting from the RAID array.)
