No the evo does not have DRAM. That's what HMB means, it uses the host's memory (your PCs RAM) instead of having its own, unlike the pro.

This has been this low twice at B&H Photo in the last 2-3 months. Both times has been on sale there for about 24 hours. I suspect this will drop below $200 around Black Friday but probably not by much. I would wait if you don't need it now. It is a good drive however for most people. I got it from B&H for a gaming laptop used as extra storage.

I don't understand the hate (thumbs down), I scrolled for an answer, like I'm sure many others before me.

Lol. Too funny... They'll stop making the NAND chips to lower supply before they let it get to that price! Samsung has already done this at least once before...

camel shows $199 is the lowest price for the evo plus, while the pro's lowest this year was $270 on amazon


I'm using mine for storage in an external case powered by laptop, so the plus doesn't require as much power from the battery

I believe it's dramless, the pro was slightly higher performing than this, but this comes with a pcie5.0*2 mode which could offer better bandwidth on certain X870/870E boards

For those wondering how the DRAM-less SSD performs vs competition: https://www.tomshardware.com/pc-c...sd-review/ . TLDR: performance not far off form Pro version. Solid perf/cap/$.
