I wonder why it is not possible to use this option?
The selected SSD does not support Full Power Mode - So is this is my Windows or specs of computer?
i5 - 4210u
RAM - 8GB
SSD - 870 EVO (2.5 SATA connection)
I believe it's the drive itself. I think support for full power mode started with the 960. You can still use rapid mode as long as you have 2GB of RAM free. With only 8GB you may need another stick.
