The old Samsung 850 EVO drives are in the Pegasus2 M4's compatibility list. The Samsung 850 has been replaced with the newer Samsung 860 EVO drives. However, the Samsung 860 is not in the M4's compatibility list. Is there any reason to believe there will be any trouble using the 860 with the M4? Has anyone used the 860 on their M4 (and if so, what capacity drive)?
