1) Card capacity
According to electronics industry standards, 1 GB = 1024 MB, 1 MB = 1024 KB. and 1 KB = 1024 bytes. If different format (FAT/FAT32/NTFS/RAW) is used to format the card, the displayed capacity may reduce slightly, as each format’s file system occupies a different initial space. Thus 32 GB may get 29.2 GB available space in an NTFS file system, but 29.4 GB available space in FAT32 formatting, while before formatting it may reach 29.5 – 29.8 GB.
64 GB = 58.50 GB raw capacity
32 GB = 29.10 GB raw capacity
16 GB = 14.50 GB raw capacity
8 GB = 7.40 GB raw capacity
4 GB = 3.70 GB raw capacity
2 GB
= 1.80 GB raw capacity
= 1.80 GB raw capacity
1 GB
= 950 MB raw capacity
= 950 MB raw capacity
512MB=475 MB raw capacity
256MB=239 MB raw capacity
128MB=119 MB raw capacity
