FDB has a substantial per-node license cost. It makes sense to beef up the hardware on individual nodes as much as possible first, then scale out to more nodes.

It would be unfortunate if their pricing model drove poor architectural decisions, but in this case that doesn't apply.

I suggested getting more storage by using the same number of nodes differently.

Ah, I mis-read your post, and was thinking you were suggesting more nodes rather than more disks. Sorry for that.

At any rate, I have quite a distaste for RAID-5, so I agree that it would be preferable to go with the higher RF instead.

Even more preferable to me would be to not use RAID-0, if FDB can just use multiple drive partitions as storage directly.

Yeah, JBOD is preferable to RAID if your workload supports it. Less overhead and less things to break.
