Something else? Generically, enterprise drives 1) have higher endurance ratings 2) are significantly more capable of fast synchronous IO 3) (IMPORTANT) don't lie about when data is actually durable I don't keep track of the details of specific drives at this point; others on the list can help with that. But I imagine we all remember the time when consumer drives tended to have great IOP rates for 10 seconds and then fall off a cliff; they also frequently pretend data is durable when it's really in a volatile cash. -Greg _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
