The actual usable capacity of the storage product is approximately 90% of the labeled capacity. This is because computers and storage products use different algorithms for calculating capacity (computers use 1G = 1024M, while storage products use 1G = 1000M). Additionally, some space is reserved for pre-installed programs before the storage product leaves the factory. This applies to all storage products. 4G ≈ 3.6G~3.8G 8G ≈ 7.4G~7.6G 16G ≈ 14G~15G 32G ≈ 28G~30G 64G ≈ 58G~60G 128G ≈ 110G~120G
