DRAM was used for caching user data in HDD.
you are referring to the SLC caching, which is a controller function that all drive do nowadays.
DRam is used to temporarily store mapping data of which block of information is stored at which flash cell (because flash cell works better when multiple cells are written in parallel, but that means data are scattered around your entire drive). as you moving data around, that mapping has to be constantly updated. due to the faster speed, dram is a more desire medium for this job. when a ssd/nvme boots up, its mapping data is copied from flash cell to dram, and update to the drive data is done in the dram and then write into the flash.
for dramless drives, they make use of host memory buffer (HMB), so the mapping content is copied and manipulated in the host memory instead of on board memory. it could be an issue if you are on a OS that doesn't support HMB, but HMB is standard as of nvme 1.2.
in modern day OS like windows that support HMB, you are likely not going to find any meaningful difference between dram vs dramless drives in performance. any performance separation is due to the controller and flash themselves, not the dram portion.
dram is more important for Sata SSD, as there isn't a HMB like standard for SATA, updating the mapping data and rewrite of that information in flash not only reduce the drive performance, but also the cell life.

If you need the extra, mega, superduper premium performance for productivity use cases that require fast reads/writes, then sure, this might be what you're looking for, given the current market.
PS: Just spotted a similarly specced MSI Spatium M482 2TB for $109 + an extra 10% off ($98): https://us-store.msi.com/PC-Compo...Me-M.2-2TB
