I suspect the behavior of the controller and the behavior of the drive firmware will end up mattering more than SAS vs SATA. As always it's best if you can test it first before committing to buying a pile of them. Historically I have seen SATA drives that have performed well as far as HDDs go though.

Hello,
We're planning another batch of OSD nodes for our cluster. Our prior nodes have been 8 x 12TB SAS drives plus 500GB NVMe per HDD. Due to market circumstances and the shortage of drives those 12TB SAS drives are in short supply.
Our integrator has offered an option of 8 x 14TB SATA drives (still Enterprise). For Ceph, will the switch to SATA carry a performance difference that I should be concerned about?
Thanks.
