ceph SSD journaling on same drive

Hello,

In my enviroment I'll use 3 hosts * 6 SSD OSD each. I wonder what will be better for me:

a) buy 128GB SSD NVMe disk(I see here such disadvantages as eg. lack of possibility to hot-swap disk when it fail) b) place 10GB partition on each SSD for journaling

What do You think? Which option will be better? Documentation says that dedicated disk for journal is pretty good idea, but I've heard opinions that on SSD OSD's there is no need to use dedicated disk for journaling.

Thanks for the answers.
