Hi, Did you try to run the following on all your nodes and compare ?
du -sh /*whatever*/cassandra/data/* Of course if you have unequal snapshots sizes remove them in the above command (or directly remove them). This should answer (barely) your question about an eventual even distribution (/!\ having a few MB or GB deviation - depending on your total data size - might happen without this being a real issue, I would say up to 5-15 % on a big enough dataset) Also, "nodetool cfstats" give you an approximation of the number of rows and the space used (to run on each node) among other useful informations. But the main thing to do is to double check your tables model to see if your workflow could create a hotspot on any of those, you should be able to guess if one of your table is badly distributed imho.
