True, I lost 2TB of storage by using Raid 0, because they are 6TB and 8TB, and with Raid 0 you get double the smaller one, i.e., my stripe shows up as 12TB. But the data on it totals about 7TB, so it's good. I will definitely look into OpenZFS. Thanks for the suggestion. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
