Drobo uses ZFS. I don't think any of them have FiberChannel interfaces. They come with Thunderbolt, gig-e, and USB-3, depending. Also, I don't think any of them are called "TD". Do you mean "5D"? Are the drives re-silvering? Do you get better results with a straight copy of a file than an rsync? -dsr- _______________________________________________ Discuss mailing list [email protected] http://lists.blu.org/mailman/listinfo/discuss
