M4 MacBook Air SSD speed?

Hi,

Appreciate if you can share your SSD speed and let us know the ssd size 🙂
Wanna know if Apple still uses single NAND for the base model this year or not.

Thank you

tomsguide tested the 256gb m4 mba on Blackmagic with write/read speeds of 1919/2891 so comparable to m3 which means double nand.
