4 GB SD card
Cheaper alternative to the SSD drive.
4 GB SD card, pSLC flash, RoHS compliant.
4 GB mSATA SSD, Phison controller, MLC NAND flash operated in pseudo SLC mode
Compatible with apu1, apu2, apu3 series system boards.
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.
