Actually, many SSD drives show much better performance for sequential write
then random writes, so you may benefit from a separate drive for commit
logs.

This my first SSD experience. With normal disks we separate commit log
from data. We have 2 SSDs dedicated to Cassandra I was wondering if we
gain a better performance if we put commit log in one and data in
another, or just use raid 0 to have both SSDs combined.
Thanks in Advance

Having commit log and data directory under one SSD works well. Though it
depends a lot on the use case. I would measure the Disk utilization and see
whether it can be on one. For most of the cases, it will work fine on one
SSD.
