Nuts, well I'll make this short:

Where did this non-sequitor come from?

Current state of FreeBSD:

ATA disks are run at the maximum transfer rate the disk, controller, and 
cable allow.  This includes things like UDMA100/66/33.
Write Caching is enabled by default now.
Filesystems have the option of running Softupdates, which almost as 
fast and _MUCH_ more reliable than async. 
ATAPI devices (CDROMs mostly) do not use DMA by default because a lot
of ATAPI devices flat out lie about what they support.  This is easily
tunable if you are _sure_ your ATAPI devices supports DMA.  It's just
common sense.

As a Tech alumni, this embarrasses me.
