Drop RAID5 and create one OSD per harddisk.

If you need to store small files consider how your applications
communicates with the storage cluster. Does your application need a
POSIX filesystem? Then Ceph may not be your first choice.

Is your application able to talk to S3 or natively to RADOS? Then Ceph
is good for you.
