Would love to see zfs test on that ratio.
Should shine with separated l2arc devices on ssd, when it gets warm.
Be sure to limit ARC size in production scenarios, leaving <insert size> for large application allocations if required.
If you intend to benchmark zfs as well.
For KVM and ZFS inside VM(s), more tuning will be required... would not recommend inside virtual machines with additional layers on top of raw(s), qcow(s) or zvol(s)
Containers on the other hand work directly, so it should be interesting to see performance on LXC with zpool configured with L2ARC and log devices.
AFAIK transparent compression with snapshots/clones etc. outside brtfs and zfs will be hard to find on linux filesystems.
So it's XFS or EXT4 all the way i'm afraid with LVM inside hypervisors for flexibility.
Stripe it over those rust disks and explore LVM caching a bit (have not used it, but it's there
)
You will have everything but transparent compression @ your disposal.
