The difference in capacity display is mainly caused by the calculation method planned by the computer operating system and the calculation method of the SSD capacity in the Controller IC. SSDs are usually calculated in the decimal system, while computer systems use the binary system. SSD: 1KB=1000Byte bytes, 1MB=1000KB, 1GB=1000MB, 1TB=1000GB Operating system: 1KB=1024Byte bytes, 1MB=1024KB, 1GB=1024MB, 1TB=1024GB Take the device with 500GB capacity indicated by SSD as an example, 500GB =500*1,000MB*1,000KB*1,000Byte=500,000,000,000Byte, but the computer calculation unit uses the binary system, so 500,000,000,000Byte will be 500,000,000,000Byte/1024KB/1024MB/1024GB on the computer identification, which is about 465GB. The fastest calculation method: Specification capacity x 0.93 = approximately equal to the actual SSD capacity.
