Hi,

I am aware that https://www.sebastien-han.fr/blog/2014/10/10/ceph-how-to-test-if-your-ssd-is-suitable-as-a-journal-device/ holds a list with benchmark of quite some different ssd models. Unfortunately it doesn't have benchmarks for recent ssd models.

A client is planning to expand a running cluster (Luminous, FileStore, SSD only, Replicated). I/O Utilization is close to 0, but capacity wise the cluster is almost nearfull. To save costs the cluster will be expanded will customer-grade SSD's, but I am unable to find benchmarks of recent SSD models.

Does anyone has experience with Samsung 860 EVO, 860 PRO and Crucial MX500 in a Ceph cluster?

Thanks!
Sinan
