<div>Way back when, I switched my recording drives to ext4. I
am considering converting them back to xfs (I am not sure
about the whole “ext doesn’t get fragmented debate”, with no
real decent way to defragment them), but not sure if there’s
any merit to doing it. Anyone have any input?</div>

Take ext4, and use the filefrag command to check how many extents a
file is using. An extent is max. 128MB. However, it is very unlikely
that you will get any noticable improvement by defraging, both XFS
and ext4 do an excellent job when reading moderatly fragmented
files.<br>

I checked it on my system, a FullHD-recording with 10GB of size
would fit into 80 extents, actually it's using 400 extents. That
does not mean it's relevant performance-wise.<br>
<br>
So, don't expect too much from optimizing the filesystem level.<br>
