i doubt this will be reliable for long time but i literally couldn't find a seller selling other brand of M2 Sata ssd in my region.
I am still waiting for it to arrive but i hope my laptop supports it.
Anyways here is some pics i took inside the laptop
Also this model actually supports an external sata ssd or hdd in the keyboard compartment but apparently pcb under my keyboard has some missing parts. Actually i really like this laptop it was really cool when it first launched but sometimes it feels very tiring to use because of its 0.80 ghz cpu, because of that i am using it with arch linux for some time, i would like to replace it with something with higher specs but it looks like i will not be able to do that for some time, thats why i decided to do a ssd upgrade.
Thank you guys for your support i will post an update when the ssd arrives.
