SSD in GPD MicroPC is replaceable. So MicroPC owners can replace the default SSD (Biwin G6327) with a higher capacity SSD or with something more reliable. I decided to upgrade to Transcend 400S.
The upgrade is quite easy to perform: remove 5 screws from the back of the device, unclip the bottom panel and you are ready to replace the SSD.
Here is a detailed instruction in case you need it.
Transcend 400S is a bit faster than the default SSD, you can see the benchmark screenshots below. The temperature of Transcend 400S is usually around 40 °C when the fan is enabled and 45 °C when the fan is disabled.
If you would decide to use the official Windows 10 recovery firmware from GPD (GPD Micro PC WINDOWS 10 Pro Factory 20190320.rar), please note, that there is an error in this archive. MicroPC won’t boot from this image. In order to make it bootable, you need to rename /WINPE/EFI/Microsoft/Boot/BCD(1) to /WINPE/EFI/Microsoft/Boot/BCD.
