It's called RAID 0 Basically it breaks the files down into two parts and writes half of it to each drive, alternating between the drives ... with a text file it might write out something like: Line 1 = Drive 1 stripe 1 Line 2 = Drive 2 stripe 1 Line 3 = Drive 1 stripe 2 Line 4 = Drive 2 stripe 2 Line 5 = Drive 1 stripe 3 Line 6 = Drive 2 stripe 3 So that if either disk crashes, you've essentially lost all the data from both disks. E.G. if disk 2 crashes, you're left with Line 1 = Drive 1 stripe 1 no data Line 3 = Drive 1 stripe 2 no data Line 5 = Drive 1 stripe 3 no data If you lose part of a file on one disk, the rest of the file on the other disk is un-recoverable. http://en.wikipedia.org/wiki/RAID If you're worried about losing data, you want RAID 1 or if you can afford it RAID 5 (or RAID 6 or a nested set RAID 1+0) -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
