Yep. A friend of mine a couple of weeks ago was involved in testing 3T disks available now in RU: - Hitachi Deskstar 7K3000: HDS723030ALA640 - Seagate Barracuda XT: ST33000651AS - Western Digital Caviar Green: WD30EZRS-11J99B0 from which only the latter, according to the tests, uses 4k firmware sectors. -- Sincerely, D.Marck [DM5020, MCK-RIPE, DM3-RIPN] [ FreeBSD committer: marck@FreeBSD.org ] ------------------------------------------------------------------------ *** Dmitry Morozovsky --- D.Marck --- Wild Woozle --- marck@rinet.ru *** ------------------------------------------------------------------------
