WD Advanced Format: do I need to do something special?

[Yuri]

WD has sectors of the size 4kB in their latest hard drives, which is 
different from the traditional 512B.

These articles assert that something special should be done in OS to 
enable high performance of such drives. For ex. WD recommends to install 
some latest drivers of particular version.
But what about FreeBSD? Should it be configured in some special way too 
for these drive to perform well?
Is it aware of 4kB sector size?
