I know you were interested in hardware RAID controllers, but out of curiosity, this is the result on a 16 x 1TB SATA linux md software RAID6 array.

Formatted xfs, with external journal on an independent SATA device, mounted delaylog,inode64,logbsize=256k,logdev=/dev/md0,noatime,pquota.

Operations performed:  0 Read, 26065 Write, 0 Other = 26065 Total
Read 0b  Written 203.63Mb  Total transferred 203.63Mb  (13.575Mb/sec)
 1737.65 Requests/sec executed

Filesystem is 44% full, kernel 2.6.39.2.

xfs_bmap test_file.0
test_file.0:
        0: [0..8388607]: 9565100544..9573489151
        1: [8388608..16777215]: 9578354176..9586742783
