eMMC Size

  • DEM-3000G, DEM-3000H: 0x3A3C00000 bytes (16GB: 4GB as internal storage and 12GB as emulated memory card)
  • DEM-3000K, DEM-3000JEC chassis K, DEM-3000L, DEM-3000JEC chassis L, CEM-3000NE2: 0xE1400000 bytes (3604 MiB)
  • DEM-3000P, DEM-3000JEC chassis P, PDEL-100x: 0xE3400000 bytes (3636 MiB)
  • PCH-1xxx, PTEL-1xxx: 0xE1400000 bytes (3604 MiB) or 0xE3400000 bytes (3636 MiB)
  • PSTV VTE-xxxx: 0xE3400000 bytes (3636 MiB)
  • PCH-2xxx, PTEL-2xxx: 0xDE000000 bytes (3552 MiB)

Maximum storage capacity supported by PS Vita is 2,199,023,255,040 bytes i.e. 2TiB (0x200 B * 0xFFFFFFFF sectors = 0x1FFFFFFFE00 B).
