Numbers are easy to calculate from RocksDB parameters, however I also don't understand why it's 3 -> 30 -> 300...

Default memtables are 256 MB, there are 4 of them, so L0 should be 1 GB, L1 should be 10 GB, and L2 should be 100 GB?

These sizes are roughly 3GB,30GB,300GB. Anything in-between those sizes are pointless. Only ~3GB of SSD will ever be used out of a
28GB partition. Likewise a 240GB partition is also pointless as only
~30GB will be used.

Where did you get those numbers? I would like to read more if you can
point to a link.
