>I think we need to go back and look at cycles per bit (DWPD is confusing because you need to know the number of years and sometimes it's not mentioned on the product page).
This work is for people developing dedicated storage arrays, not your laptop. Datacenter optane is good for 60 DWPD. Given that it is most frequently used as a caching layer, it's extremely unlikely you'd exceed that in a well designed system.

>Atleast SATA I can use in my laptops/desktops/consoles etc. Also nobody is looking at CPU usage of NVMe vs. SATA!
Literally every storage vendor in the market is looking at CPU usage of NVMe vs. SATA. There's a reason they benchmark in "a standard 2U system" and not a Dell Laptop or Desktop.
- bullen 5y ago60 DWPD was the original optane development result, but the final product that we can buy is 10 DWPD. My issue with DWPD is that you can have the firmware complexity pretend the drive is good while losing space... I prefer to have really solid "100.000 writes per bit" 50nm SLC flash memory cells with less magic. If everyone is measuring NVMe vs. SATA how come I can't find anything interesting when googling? It's only popular articles about the high level difference, "the plug is different"... I would like benchmarks with apples to apples CPU usage while having alot of concurrent data in flight simoultaneously!
