* We removed the DC JACK power socket of X857 V2.0, X857 V2.0 is powered via USB 3.0 connector.
* We use shorter copper spacer to connect Raspberry Pi 4 and X857 V2.0, which reduces the height of the entire product, so the matching metal case [[X857-C3]] is shoter 3mm than [[X857-C1]];
* We have solved After our test, X857 V2.0 can connect to 2.4G wifi in seconds without the EMC interference issue between Raspberry Pi 4 and USB3metal case.0 device ON However, '''if X857 V2work with a metal case or external USB 3.0devices such as a mouse or keyboard, you may still need to use Ethernet or 5G AP. '''
* But if you use a metal shell like [[X857-C3]], then you can only use 5.8G wifi AP, 2.4G wifi will not be available(be shielded by metal case);
* As a Raspberry pi NAS device, we advised that you use ethernet network to replace wifi, this will be more stable and reliable.
* X857 V1.2 version supports TRIM but not UASP supported ONLY for X857 , '''V2.0, do version supports UASP but not support TRIM. '''
