This is a Seagate ST3000DM001, all one volume, for my sister's DVR on 
which I've been doing this volume recovery work.  The default setup that
mkfs.xfs returns with no parms supplies is this:

meta-data=/dev/sda1              isize=256    agcount=4, agsize=183141568 blks
         =                       sectsz=4096  attr=2, projid32bit=0
data     =                       bsize=4096   blocks=732566272, imaxpct=5
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0
log      =internal log           bsize=4096   blocks=357698, version=2
         =                       sectsz=4096  sunit=1 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0

and that takes about 3 minutes to mkfs a 3TB drive.

Anyone have some thoughts they wish to cast upon the waters about either part 
of that?
