I believe most/all shipping drives of 1TB and smaller still have native 512 byte sectors, dependent on specific vendor/model line of course. It's mainly the 1.5TB and up drives with the hybrid 512/4096 byte sector abomination. It would be far more optimal if they'd just ship native 4K sector drives wouldn't it? Isn't most of Linux already patched for pure 4k sector drives? Is XFS ready for such native 4k sector drives? Are the various RAID cards/SAN array controllers? -- = Stan _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
