==Matching Metal Case for X855==
The case for Raspberry Pi 4 with X855 hasn't released yet, but it will release in the near future.
==Packing List==
1 x X855 V1.3 Expansion Board
1 x USB 3.1 connector
1 x Install Screws pack (6x M2.5*6 ;4xM2.5*12+6 ; 4x 2.5*5)
==Test Data==
Test results based on SAMSUNG MSATA 860EVO 250G SSD. We used 3 different software to test it, since this is transferred via USB, it cannot read and write 500M/S.
