Key Differences:
- Performance: The Lexar NM790 takes the edge with up to 7,400 MB/s read and 6,500 MB/s write speeds. The SN7100 hits up to 6,800 MB/s read and 5,800 MB/s write, depending on the capacity. [1, 2]
- Endurance: Lexar offers higher Terabytes Written (TBW) ratings (e.g., 1,500 TBW for the 2TB model) compared to standard drives, giving it a longer expected lifespan for heavy writing tasks. [1, 2, 3]
- Efficiency: The WD Black SN7100 excels in power efficiency, which makes it a phenomenal choice for laptops or handheld gaming devices like the Steam Deck or Legion Go. [1]
- Heat: WD's controllers often run cooler, giving the SN7100 an advantage in tighter, poorly ventilated spaces. [1]
Which one should you pick?- Choose the Lexar NM790 if you need an affordable, blazing-fast drive for your primary desktop setup or PS5 where raw speed and endurance are the priority. [1, 2, 3, 4]
- Choose the WD_BLACK SN7100 if you are putting the drive into a laptop, a portable console, or a compact HTPC where thermal management and battery life matter most.

Looking at sustained speeds the sn7100 is in the SLC mode for much longer, even the avg speeds after that is about the same, making the sn7100 better

Looking at all the benchmarks is basically better in every benchmark.
Don't use AI for comparing ssds again please, it just uses the wrong things to compare ssds, doesn't use actual benchmarks but advertised speeds, which u won't be getting to in real life scenarios, only synthetic useless benchmarks, the sn7100 uses outright better components as it uses the polaris 3 (which is a great high end gen 4 controller) and bics8 which is the best nand, used by the best ssd itw as of right now (mp700 pro xt)
