Still, I don't think we'll be using them in RAID 6; mostly, either for backups, or for just holding honkin' large datasets. One issue, for example, are the Penguin servers that we have, with bloody Supermicro m/bs (see that thread), and they demand the short TLER that WD Greens and Blues don't do - they will keep trying for something like 2 *minutes*, not six seconds. These seem as though they might work, even with those picky servers. mark _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
