The DRAM chip holds a lot of important data, not just temporary data that needs to be transferred to NAND storage. DRAM also holds the drive's FTL or Flash Transition Layer, which is used as a map to see where data is stored on the drive. If the FTL is corrupted, the entire SSD could also become corrupted.
Thankfully, some SSD manufacturers have countermeasures in place for such an occasion. One example is a technique used by Samsung that employs journaling to keep as much data intact as possible during a power outage. Journaling allows SSDs to keep track of what changes need to be made to the SSD from the OS's file system before they happen. When a power outage occurs and data is lost in the DRAM cache, the SSD knows what data was already transferred to the NAND (and what data was lost directly from the journal). "

ALSO THIS:
"Russ Bishop, a programmer at Apple, noticed some interesting and rather worrying behavior from some NVMe SSDs when he tested the impact of a power outage on the cached data.
Out of the four SSDs that Bishop tested, two of them worked perfectly as they should, preventing data loss. These two models are:
Samsung 970 EVO Plus
WD Red SN700
The two other models that lost data are:
SK hynix Gold P31 2TB
Sabrent Rocket 512"

I just put the SK Hynix in my Lenovo 5 pro Laptop. Runs cooler than most chips and I got incredible speed benchmarks. Very happy with it. No need for a heat-synch with he Hynix.
It has no DRAM but research shows its performance to be on par with DRAM cache.

Not sure the downvote... legit question, I'm buying it for an external storage, would like to have the most capacity out of the 1TB.

SN770 is also not the fastest in the WD tier. The SN850 is. But the SN770 is newer which runs cooler and more power efficient so good for laptops if that is where this nvme is going to.
