Subject: Can Cassandra work efficiently with multiple data directories on multiple disks?

Hi there,

I have the following configuration:
data_file_directories:
    - /data1/cass
    - /data2/cass
    - /data3/cass
    - /data4/cass
    - /data5/cass
    - /data6/cass

and each directory resides on a separate stand-alone harddisk. My questions are:
1. Will Cassandra split data evenly on multiple disks?
2. How will Cassandra work if one of the disk is full?
3. What's the best configuration strategy if you have multiple disk per node?
Thanks
