Not exactly. A true RAID 0 (or a striped set) alternates writing each block from one disk to the other. This increases performance because 2 chunks of data can be written at the same time - one chunk to disk 1, one chunk to disk2, etc. Joining partitions together, or extending a volume, is not RAID 0. This does not necessarily increase performance, because data typically won't be written to the second disk until the first is full. In both scenarios, your useable space equals all your disks combined, but only the striped set improves performance. _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
