get Samsungs 2tb for 149.XX. Samsung has the MOST Tbw (terabytes written- longevity)

Dramless SSDs are just fine for the intended purpose. Having no DRAM means less complex pcb, smaller/simpler flash controller, lower power draw (especially in idle) and overall lower cost (most noticebly on smaller capacities).
Obviously having no dram kills some performance (random writes especially) and consistency, so where performance is critical, you're not gonna use such a drive.
As for durability/endurance of such drive; it highly depends on the workload. Having no dram does not inherently mean less endurance (dram is only meant for mapping tables, not for write caching or something similar) so mapping tables on the actual flash have to be updated regularly anyway, regardless if drive has dram or not. If drive has lots of random write workload, having dram does speed up things and some flash translation layer updates can be cached to the dram and flushed back to flash at a delay (less updates to the actual flash).
Less endurance for dramless drives get thrown around a lot, but the bigger factor here is not the lack of dram itself, but just the fact, that such drives are usually lower cost, which means lower bins of flash are used and simpler controllers don't do as good of a job with ECC. This results in lower rated endurance.
Honestly, if implemented correctly, dramless drives are prefectly fine and shouldn't be disregarded.

I'm waiting for the 2 tb SATA 2.5 Inch Internal SSD drives to come down to about $100. I don't think I'll need D-ram cuz I'll be using it for file storage on 2nd drive slot in my laptop. The 1st drive slot will definitely have D-ram. I don't mind spending $20 bucks more for more price of mind of endurance.

but the SN850 and SN850X are much better

Don't really need dram anymore with these modern controllers. They are being phased out.
Anyone have benchmarks or articles displaying this?
