I fiddled with the BIOS, now I see :

# dmesg | grep wd
wd0 at atabus0 drive 0
wd0: <Hitachi HDS721010DLE630>
wd0: drive supports 16-sector PIO transfers, LBA48 addressing
wd0: 931 GB, 1938021 cyl, 16 head, 63 sec, 512 bytes/sect x 1953525168 
sectors
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133)
wd0(ahcisata0:0:0): using PIO mode 4, DMA mode 2, Ultra-DMA mode 6 
(Ultra/133) (using DMA)
wd1 at atabus1 drive 0
wd1: <Hitachi HDS721010DLE630>
wd1: drive supports 16-sector PIO transfers, LBA48 addressing
wd1: 931 GB, 1938021 cyl, 16 head, 63 sec, 512 bytes/sect x 1953525168 
sectors

wd1(ahcisata0:2:0): using PIO mode 4, DMA mode 2, Ultra-DMA mode 6

And lo ...

That's MUCH better!

Stupid PC BIOS defaults ...
