Hello, I've got 3 1.5TB drives that are using the "Advanced Format" from Western Digital, see the link for details: http://www.wdc.com/wdproducts/library/WhitePapers/ENG/2579-771430.pdf This "Advanced Format" basically means the sectors size on disk is changed to 4k in stead of 512k. I'm wondering if freeBSD 8.0 using ZFS raidz and drives like these will work properly, I've seen a lot of articles and postings about partitions not being properly aligned with the physical disk layout and suffering big performance hits. My question is; should I worry about these issues or does ZFS already align the data on a 4k border? My setup would be 3 * 1.5TB WD drives (WD15EARS) using the whole drive for a raidz pool. Thanks, Rob Evers ***deze e-mail is gescand door Onlinespamfilter.nl***
