* reads, Memtable flushing,
compacting and repairing on the data volume.
The only way to be sure is to test both setups.

*Subject:* Re: idea drive layout - 4 drives + RAID question
Have you considered running RAID 10 for the data drives to improve MTBF?
On one hand Cassandra
For a server with 4 drive slots only, I'm thinking:
either:
- OS (1 drive)
- Commit Log (1 drive)
- Data (2 drives, software raid 0)
vs
- OS + Data (3 drives, software raid 0)
- Commit Log (1 drive)
or something else?
also, if I can spare the wasted storage, would RAID 10 for cassandra data
headaches
should one of the drives fail. You can already distribute the
individual Cassandra column families on different drives by just
setting up symlinks to the individual folders.

0 for data. The raid does give you good performance benefit, and it can be
convenient to have the OS on a side drive for configuration ease and better
MTBF.
