In my understanding nearly the only relevant number is the number of cache flushes a drive can handle per second, as this determines my single thread performance. Has anyone an idea what numbers I can expect from an Intel X25-E or an OCZ Vertex 2? -Arne _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
