I can confirm,

As they "emulate" 512 sectors, yes they will "work", _but_ not as well 
as Hitachi and some other brand/models, and definitely not recommended 
with expanders.

Also sector alignment may need to be tinkered to improve performance.

The major issue is the fixed and very long TLER setting, which will 
cause driver time-outs, especially under load.

Solaris doesn't tolerate this well, and linix isn't too fussed with raid 
sets of them either.


I managed to lock up a server last week with sata bus errors on a triple 
esata setup with wd20ears disks (raidz LTO5 alternative) with bacula.
