I think the value of the r6gd (assuming cpu is good compared to intel) is
more cpu, not disk.
I'm not running on spark the cassandra servers, and having more cpu cores
in my cluster will sure help. It all depends on the workloads, some
workloads need more io, some cpu.
i3 servers are great

I'm aware. I did use r6gd.2xlarge in my example. :)

it's not the same, notice I wrote r6gd, these are the ones with nvme, i'm
looking just at those.
I do not need all the space that i3en gives me (and probably won't be able
to use it all due to memory usage, or have other issues just like you
mention), so the plan is use the big enough r6gd nodes,
The instance types you refer to are contradictory so I'm not really sure if
this is really about Arm-based servers. The i3en-vs-r6 is not an
apples-for-apples comparison.
The R6g type is EBS-only so they will perform significantly worse than i3
instances. R6gd come with NVMe SSDs but they are
If anyone has tried it hasn't been publicized. I wouldn't anticipate any
real issues because it's all Java, but given we don't test on ARM you
should definitely test it out before making the switch in prod.
