Fill factor is a measure of how efficiently a storage device is using its space. It is calculated by dividing the amount of data that is stored on the device by the total capacity of the device. A fill factor of 100% means that the device is completely full, while a fill factor of 0% means that the device is empty.
Fill factor is an important metric to consider when choosing a storage device because it can affect the performance of the device. A device with a high fill factor may be more likely to experience performance problems than a device with a low fill factor. This is because a high fill factor means that there is less free space on the device, which can make it more difficult for the device to read and write data.
