One case where I have used large stripe sizes (though not with hardware raid and not with FreeBSD) is with concurrent small reads (small = seek is the dominant cost) on top of a device of many drives. In these cases you want to minimize the chance that a particular read will span multiple stripes, such that only a single drive will take a seek hit for a given request. This in turn maximizes actual physical concurrency when under high load (=high incoming request concurrency). -- / Peter Schuller PGP userID: 0xE9758B7D or 'Peter Schuller <peter.schuller_at_infidyne.com>' Key retrieval: Send an E-Mail to getpgpkey_at_scode.org E-Mail: peter.schuller_at_infidyne.com Web: http://www.scode.org
