Yeah, they are. Most likely, they don’t have some sort of super-cap. A power-failure might totally toast the filesystem. These disks are - IMO - designed to accelerate read-operations. Their sustained write-performance is usually mediocre, at best. They might work well for small data-sets - because that is really written to some cache and the firmware just claims it’s „written“, but once the data-set becomes big enough, they are about as fast as a fast SATA-disk. https://www.tomshardware.com/reviews/samsung-970-evo-plus-ssd,5608.html
