Yes, there should a separate partition per OSD. You are probably looking at
10-20GB journal partition per OSD. If you are creating your cluster using
ceph-deploy it can create journal partitions for you.
"The expected t
-8 OSDs for 400GB SSD.
Should there be different partitions for each OSD on the SSD?

I would suggest splitting OSDs across two or more SSD journals (depending on
OSD write speed and SSD sustained speed limits)
e.g 2x Intel S3700 400GB for 8-10 OSDs or 4x Intel S3500 300GB for 8-10 OSDs
(it may vary depending on the setup)

If you RAID-1 SSD journals they will potentially "wear out
I am thinking of having ceph journal on a RAID1 SSD.
Kindly advise me on this, does the RAID1 SSD for journal make sense? ___
