I will be installing Xubuntu 24.04.3 on a newly built system having two
4TB Samsung M.2 SSDs which will be mirrored using RAID-1. My question is
what is the better way to set up the mirror. I'll have 128GB of RAM and
will be using a swapfile after installation.
Method #1: After the UEFI partition is created on both disks, create GPT
/boot, / and /home partitions on each SSD and then create
three separate mirrors:
md0: /boot
md1: /
md2: /home
Method #2: After the UEFI partition is created on both disks, mirror md0
using the rest of the free space. Then create GPT partitions
directly on the mirror:
md0p1: /boot
md0p2: /
md0p3: /home
This will be a straightforward desktop workstation, with no encryption or
support for multiple OS installs. Are there advantages or possible pitfalls
with either approach?
I'm also considering eliminating the boot and home partitions and just
using a single root partition which feels strange after using UNIX for over
40 years. From a raid perspective does this also have advantages/pitfalls?
Thanks.

What about:
sda1 and sdb1 for EFI no raid sda2 and sdb2 RAID-10 with -f2 option (diffrent offset that gives double speed of read and single speed of write)
md0: LVM and on top of LVM you can create partitions with XFS filesystem. XFS allows you to realtime grow partitons.
