Should include:

1. Dual Ext4 + external 32GB journal X4 pcie SSD (the prior winner of benchmark surveys)

2. Bare F2FS after a trim and SSD vendor software cache flush operation (it should be slower, but knowing how much slower on identical hardware could be interesting.)

3. DRBD across a 48U 100Gbps host rack (single X4 pcie data drive per host, OS on primary)

4. CephFS across a 48U 100Gbps host rack (single X4 pcie data drive per host, OS on primary)
