Well,with bluestore, no more journal and double write.
So, without ssd, performance will be better.

You can still have ssd for fast ack, but something like a intel s3500 should be enough, 
because they won't write too many things.

Yah I know :( Intel 530's initially, then Samsung 850 Pro. The 3700's 
were out of our budget range for the size of our cluster. 

Wasn't to happy with the direction Ceph is taking either, to me the 
required hardware and complexity seems to be moving out of the range of 
the small business setup and I'm not happy with the concept of them 
moving it bare disk access (Bluestore).
