I was going with a low perf scenario, and I still ended up adding SSDs. Everything was fine in my 3 node cluster, until I wanted to add more nodes.
Admittedly, I was a bit aggressive with the expansion. I added a whole node at once, rather than one or two disks at a time. Still, I wasn't expecting the average RadosGW latency to go from 0.1 seconds to 10 seconds. With the SSDs, I can do the same thing, and latency only goes up to 1 seconds.
I'll be adding the Intel DC S3700's too all my nodes.

If you’re going with a low perf scenario I don’t think you should bother buying SSD, just remove them from the picture and do 12 SATA 7.2K 4TB.
