Yes, the Intel® DC 3700 SSD uses capacitors to write the data from the buffers to NAND during a power loss.
“The drive saves all cached data in the process of being written before shutting down, thereby minimizing potential data loss.”
For further information you may check the following document:
I've also read those statements in the datasheets and specifications. My concern is with the statement "in the process of being written." This does _not_ state that all buffered data is written.
Can Intel provide a more complete description of what gets flushed upon unexpected power-loss, just as the competitor has listed in the above picture? I'm just concerned because the amount of bulk capacitance on this SSD can power the drive for 55 seconds.
Note that I'm taking your word for it, but if they don't behave like you say they do during power cut testing (by exhibiting errors or shorn writes) we'd be forced to return these drives. Maybe you can run and go check with one of your FTL firmware engineers or FAEs?
Just to confirm, if there are a full queue depth of commands that have been acknowledged with an ATA 50/00h status, and I cut power at random times, I will get correct data back?

Let us check about this.
It is confirmed; all acknowledged writes will be properly written to the SSD.
