Hi,
I am looking for the best suitable SSD drives for a Proxmox VE Ceph cluster in

Based on features (power loss protection) and price, the

When you are to compare specs for SSDs or HDD's for that matter to be used in
a remote storage what do you consider most important? Max read/write MB/s
or read/write IOPS?
Personally I should think when we are looking at SSD's max read/write MB/s is
irrelevant since the network will always
Hi,
currently with firefly, you can expect around 3000-5000 iops by osd,
so any good ssd should be ok.
Recent discussion on ceph mailing list, said that they have remove a lot of
lock and bottleneck is current master git. (with performance x5)
The Crucial MX100 provides 90k/85k IOPS. Those numbers are from specs,
so I am not sure if you can get that in reality?
No, I think you can reach 90K maybe for some seconds when they are empty ;)

For me discard doesn't work with virtio disks. I did with scsi and
virtio controller. Alexandre how it works for you?

It's working with virto-scsi,
but you also need discard support in your guest filesystem,
and also for your storage
(should work with ceph, iscsi block storage, local raw/qcow2 on top of host
with filesystem with discard).
It don't work with nfs, lvm(local or on top of iscsi).
