The M500 was released over 2 years ago a lot has happened in the SSD market since then. New controller, new NAND-Chips (M500 - 20nm, MX200 - 16nm). I will take a very close look on the performance though and will definitely compare with non-ssd-journals. Thanks for the heads up, the nice thing about those 250GB SSDs is.. I can just put them into desktops or notebooks if they are not suited for the cluster. ___ Dominik _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
