Yes, I think the 'EARS' series are the first WD consumer drives using the new 4K sector 'Advanced Formatting': http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-701229.pdf : "Advanced Formatting Technology being adopted by WD and other drive manufacturers to increase media format efficiencies, thus enabling larger drive capacities. (WDxxEARS and WDxxxxAARS models only)" I saw some discussion of performance and alignment, but it was in relation to Linux, perhaps it doesn't relate to Solaris?: http://www.gossamer-threads.com/lists/linux/kernel/1039141 Cheers, Simon -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
