Is it good to have a single separate physical SSD disk (not raid-0) for commitlog?

@Mahdi_Kamali: Is it good to have a single separate physical SSD disk (not raid-0) for commitlog? Does it give better performance? (Assume we have 6 same SSD disks with raid-0 for /var/lib/scylla directory)

@avi: It’s better to share the data and commitlog disks so that the available bandwidth can go where it’s most needed.
