Wouldn't it be sufficient to fire 4GB worth of any data (for instance some brand new hexadecimal zeroes freshly out of /dev/zero) with dd? Like

Code:
dd if=/dev/zero of=/the/raid/somefile bs=1G count=4

True, this will be off by the overhead of /dev/zero, wouldn't that be negligible given the bandwidth of disks and the memory interface (which are apart some orders of magnitude)?

I hope this helps.

NAME

       dev - Device name file system

DESCRIPTION

       The  dev  filesystem  manages  the  name  spaces  of devices under the Solaris operating environment. The global zone's instance of the dev
       filesystem is mounted during boot on /dev.

       A subdirectory under /dev may have unique operational semantics. Most of the common device names under /dev are	created  automatically	by
       devfsadm(1M).   Others,	such  as  /dev/pts,  are dynamic and reflect the operational state of the system. You can manually generate device
       names for newly attached hardware by invoking devfsadm(1M) or implicitly, by indirectly causing	a  lookup  or  readdir	operation  in  the
       filesystem to occur.  For example, you can discover a disk that was attached when the system was powered down (and generate a name for that
       device) by invoking format(1M)).

FILES

       /dev    Mount point for the /dev filesystem in the global zone.

SEE ALSO

       devfsadm(1M), format(1M), devfs(7FS)

NOTES

       The global /dev instance cannot be unmounted.
