The author tests SSDs during power outages and concludes that Intel SSDs (which are notably pricey) are the only way to be thoroughly sure of data consistency. Though for everyday users, having SSD’s fail after thousands of power outages is probably not relevant. For home users, I’d lean towards a bunch of smaller non-Intel SSD’s in a RAID5/6, with a journaled file system and plenty of backups.
“Right now, there is only one reliable SSD manufacturer: Intel. That really is the end of the discussion. It would appear that Intel is
the only manufacturer of SSDs that provide sufficiently large on-board temporary power (probably in the form of supercapacitors) to cover writing
back the entire cache when power is pulled, even when the on-board cache is completely full.”
