Replace 3TB drive with 1 TB drives (Ceph)


Feb 13, 2022
My ceph cluster has 3 3TB and 3 1TB drives with SSD WAL and DB. The write speeds are kinda meh on my VMs, from what I understand the 3 TB drives will get 3x the write request of the 1TB drives. Is my understanding correct ? and would it be better if I swapped my 3TB with 1TB drives making it 2 1TB drive per host instead of 1 3TB and 1 1TB.
