4 GB SD card|
||sd4b = 4 GB SD card, pSLC flash, RoHS compliant
||4 GB mSATA SSD, Phison controller, MLC NAND flash operated in pseudo SLC mode
||apu1..4 series system boards
||Upcoming production batches (from 5/2018) will NOT support CPRM (content protection for removable media).
||pSLC / pseudo SLC means that MLC flash (2 bits per cell, 4 voltage levels)
is used in SLC mode (1 bit per cell, 2 voltage levels). This reduces capacity
by half, but ensures better endurance and write performance.
