The @code{RAID_TYPE} option will help you to break the 2G/4G limit on
Operating Systems that don't support big files. You can get also more speed
from the I/O bottleneck by putting @code{RAID} directories on different
physical disks. @code{RAID_TYPE} will work on any OS, as long as you have
configured @strong{MySQL} with @code{--with-raid}. For now the only allowed
@code{RAID_TYPE} is @code{STRIPED} (@code{1} and @code{RAID0} are aliases
for this).
