If you use this trick on UFS, the performance will not be stellar; however, you have created nearly continguous files. But in ZFS, the data of the two files will be randomly located; everytime you write to the files, the data will move around. This is not at all what ZFS expects. You should try again using a "zvol" by using zfs create -V.
