problems with KINGSTON_SFYRD4000G disks in ceph cluster

[Lamarus]

Hello Community. Does anyone have KINGSTON SFYRD 4000G drives in ceph cluster? We have built a cluster on them and are seeing very high latency at low load. There are no network or CPU issues.

Ceph version is 17.2.7, cluster is built on LACP inter 25G network cards, Dell R450 servers, 256Gb ram per node.

The problem is these Kingstons are office or gaming drives, they are not inteded for serious work. Buy better drives.
