Disk mirroring in Linux -- MD-RAID or LVM? Advantages and disadvantages?

20 Jan 2021

      Hi all;

In Linux I can do software RAID using LVM or with MD (i.e., mdadm) as a
basis.  I'm currently thinking of a simple mirror of two conventional
SATA disks.

The machine is being built to do a compute-workload involving
examination of many small(ish?) files, and will not be a desktop or a
recreational/gaming machine.  I don't know anything about the files or
how they'll be examined.

How would YOU setup a simple mirror in whatever Linux you use?  Why do
you prefer your selection?

Thanks,

--MCV.
