Absolutely. Never use PATA slave config if you care at all about performance. > > i/o to/from the disk's cache will be marginally slower but you want to > > disable the write cache for data integrity anyway. > > > Do you? I though ZFS enabled the drive cache when it used the entire drive. I think you're right, I think what i was thinking of was that ZFS (and anyone else, really, but ZFS is where i've heard about it) wants to be awful sure that the drive actually flushes its write cache when you ask for it. Regardless, the speed difference is marginal. danno -- Dan Pritts, System Administrator Internet2 office: +1-734-352-4953 | mobile: +1-734-834-7224 _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
