It's more significant than that. Drives aimed at the consumer market are at a competitive disadvantage if they do handle cache flush correctly (since the popular hardware blog of the day will show that the device is far slower than the competitors that throw away the sync requests).

It wouldn't cost any more for commercial vendors to implement cache flush properly, it is just that they are penalized by the market for doing so. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
