curiosity, this is the result on a 16 x 1TB SATA linux md software RAID6
array.

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
