Bill, You have RAID 0, which means that half of your data is stored on one drive, and the other half is stored on the other drive. Your system will read and write from both drives simultaneously, meaning that parts of one file could be on one drive and the rest on the other. This, theoretically, speeds up read/write times. Here's my opinion: You don't need it. Should you have a drive failure, you'll pretty much lose everything on both drives. While there are performance improvements, I can't think of why a single user on a desktop machine needs them. RAID 0 is intended for high throughput environments. RAID 0 should also be mirrored, with either an identical RAID 0 setup or a single drive that's twice the size of the other two. You're much better off mirroring those drives so that if you have a failure you haven't lost anything. Add drives as needed for additional storage. -- Scott Loveless http://www.twosixteen.com/fivetoedsloth/ -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
