The http://www.intel.com/content/www/us/en/solid-state-drives/solid-state-drives-710-series.html seems to qualify: "Enhanced power-loss data protection. Saves all cached data in the process of being written before the Intel SSD 710 Series shuts down, which helps minimize potential data loss in the event of an unexpected system power loss." > Extreme write IOPS claims in consumer SSDs are normally based on large > write caches which can lose even more data if there is a power failure. Intel 311 with a good UPS would seem to be a reasonable tradeoff. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
