About NVME M.2. SPEC

Hi guys,

What is the PCIe spec of MiniBook’s NVME? I installed a PCIe x3 NVME SSD.
CrystalMark test results limited the speed to 1,000MB/sec. If I installed it in my computer, it can transfer over 2,000MB/sec. It looks like support only PCIe x1. Does it right?

You can check supported version in aida64 or cpuz, but it can be hardware downgraded to x2,x1.

Thanks,

I tried to get the information of M.2 Interface used by CrystalDiskInfo. It was working on PCIe 3.0 1x. I do not understand why it working 3.0 1x…

Dear friend,

I already knew that eMMC of MiniBook has not too bad when I using it for general jobs. I installed NVME SSD in my MiniBook for storage performance improvement. But I got very disappointing results.

According to your attached images, it looks like M.2 is installed SATA SSD. The maximum transfer performance is only 550MB/sec. It is different.

Maybe x2 is used for something else or not used at all, and x1 is the only PCIe implemented on this board. :man_shrugging:

OMG … I hope CHUWI will fix its PCIe problem(?) with something like a BIOS update(or driver update). If they will can …
