i have come across an interesting article at : http://www.anandtech.com/IT/showdoc.aspx?i=2859&p=5
it`s about sata vs. sas/scsi realiability , telling that typical desktop sata drives ".....on average experience an Unrecoverable Error every 12.5 terabytes written or read (EUR of 1 in 1014 bits)." since the 1TB drive is out very soon, this really makes me afraid of data integrity on my backup disks, so the question is: will zfs help detect/prevent such single-bit errors ? i`m somewhat sure, that it will help if i use raid1 setup with ZFS - it`s self healing will detect those single-bit-errors and correct this - but what about single disk setup ? can zfs protect my data from such single-bit-errors with a single drive ? regards roland This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
