 Hi Suresh,
Welcome to Cassandra!
Node density is an important topic with Cassandra. Depending on the node type, 
data usage, and your operational expertise, you can go somewhere between 1TB 
and 3TB of data size. If you just start, stay below of 1TB to avoid troubles. 
Storing too much data on a node make it difficult to run repairs, to replace 
node, add nodes etc....
As you plan to use STCS, you should know that in the worth case scenario, 
during major compactions, you might need about twice the volume size of your 
data (on a given node) to complete the compaction, so make sure you plan for 
that too.
Final note, concerning the type of disk, you should be perfectly fine with SSD 
RAID0. If your application is read intensive, and you want to have the lowest 
latency possible, you could go with the more expensive NVME. If that was the 
case, you should also look at using LTCS instead of STCS.
Hope this help!
Cheers,Christophe

Hi,
I am new to Cassandra. Is there any recommended maximum data size per node for 
Cassandra 3 with STCS. Also any recommendation on SSD RAID 0 vs NVME JBOD?
ThanksSuresh
