Write performance of RAID-1 is approximately as good as a simple drive, which is good enough for many applications. > Also keep in mind that some software RAID implementations allow more than > two drives in RAID 1, most often called a "mirror set".

Some of my RAIDs are N-way RAID-1 because of the superior read performance. --Mike Bird -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
