This is 4tb so chances are you are storing data not doing something intensive so being dram-less isn't that big of a deal, in my opinion

Yep. $220 is the normal price. It gets inflated to $299 for a bit then drops back down. I'm waiting for it to go lower.

the one that was on sale was the Lexar SE Play made just for costco, not the same as this model.

The Lexar SE Play is QLC uses InnoGrit's IG5236 controller, runs hot, but the price and heatsink and costco return policy negates that

This Lexar NM790 is TLC 3D NAND uses Maxio MAP1602 controller the price has been 219 since launch at Costco, and it's normally about ~$10~20 less than competitor.

For those shopping for NVME M.2, DDR5 ram, prices are not going to come down anytime soon. It's not just AI demand, cause large AI infra actually uses just as much HDD (spinning drives), tariffs and supply chain shifts and poor trade economy are the upstream causes.
(Also imagine all the people upgrading to NVME M2 (new mobo) and NVME being much faster than SATA SSD. )

I have the 8TB version of this drive and it's the only drive I've found that won't overheat in a basic USB 3.1 Gen2x2 enclosure. Also, it sips power, so I imagine it would be great for portables where battery life is needed. It would make an ideal PS5 upgrade drive too.

You may wonder why people are downvoting your comments. It is because the information you are parroting is misunderstood and outdated. Somewhere around 2019/2020 DRAM became less far less relevant for SSDs with the widespread adoption of Host Memory Buffer technology in NVMe SSD's. HMB allows DRAM-less SSD's to use a small portion of the computer's main RAM as a buffer, significantly improving their performance and making them competitive with DRAM-equipped drives for the vast majority of consumer applications,

People can downvote me all they want, I really don't care. I merely stated a fact of the matter, it's no different than any other deal here when details are left out and other comments fill them in. Remember the no HDMI days? I do.

How is this any different than the host OS using ram to cache reads and writes? Not really a development

This should be fine as a local Plex media server drive, right?

The main difference is that OS is caching the files while the HMB is caching the lookup tables for the SSD's data blocks. HMB is probably around 10% slower on writes than equivalent SSDs with DRAM because of the slower updates to the lookup tables; likely no effects on reads.
