GB (Gigabyte) and GiB (Gibibyte) are two different digital data storage scales defined by the International Electrotechnical Commission (IEC).
In short - GiB is base 2, GB is base 10.
- GiB = 2 to the 30th power (1,073,741,824) bytes (base 2)
- GB = 10 to the 9th power (1,000,000,000) bytes (base 10)
USABLE CAPACITY (FAT32)
When you mount the SSD to a computer, the computer may show a different storage capacity than the capacity in the SSD name. The following reasons may cause different storage capacity to be displayed:
- Each operating system calculates storage capacity differently.
- Each operating system may measure the storage either in Gigabytes (GB) or Gibibytes (GiB).
- The SSD format (FAT32 vs other formats) affects the capacity.
The table below shows the storage capacity in GB and GiB for each RED MINI-MAG (when formatted as FAT32).
| SSD Type | Usable Space (GB) | Usable Space (GiB) |
| RED MINI-MAG 120GB | 120.02GB | 111.78GiB |
| RED MINI-MAG 240GB | 240.03GB | 223.54GiB |
| RED MINI-MAG 480GB | 480.05GB | 447.08GiB |
| RED MINI-MAG 960GB | 960.08GB | 894.14GiB |
| RED MINI-MAG 1TB | 1024.08GB | 953.75GiB |
