btw, forget to add:
H10 512GB: R=2300MB, W=1300MB, 150TBW, 5800mW
H20 512GB: R=3400MB, W=2000MB, 185TBW, 170mW
Obviously H20 wins with a big margin here

Lately I see that there are lots of Intel Optane and NVMe drives on sales (because they are discontinued), and you may consider buying; P4800X 375GB U.2 is like around US$200. P1600X 118GB m.2 is like US$60. And H20 1TB is now US$50, but there’s also P4511 2TB at US$70.
It’s not that easy to get them for this cheap in Europe but it can be done I think.
Edit: nope, can’t buy these cheaply here.
我直接使用了作者的dtb,替换后发现无法开机,后来发现是因为我的系统是6.1内核。使用5.10内核后成功识别两个储存空间。

但是现在是TF卡启动,我想把系统装到32G傲腾里,但是陷入鸡生蛋蛋生鸡循环了
