I see that the wm servers use RAID 0 quite a bit, and
wondered why not
JBOD?
Does RAID 0 perform better, or was there some other reason?
Striping data over multiple disks usually allows equal utilization of all
disks in a RAID0. Usually, there are some hot spots in a database, where
most write and read operations happen, and some colder areas, for example
very old revisions. Since our database grows continuously, hot spots usually
are at the end of the database file. With concatenation this would be on
only one disk, while other disks were idle.
